Em particular durante as assembléias da Sociedade Brasileira de Finanças e da Sociedade Brasileira de Econometria existe um diálogo bem intenso entre os editores e os membros das sociedades, e muitos comentários e sugestões são incorporados através desses diálogos. &lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/26274345-4788459340363881193?l=raciocioniosespurios.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://raciocioniosespurios.blogspot.com/feeds/4788459340363881193/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=26274345&amp;postID=4788459340363881193&amp;isPopup=true' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/4788459340363881193'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/4788459340363881193'/><link rel='alternate' type='text/html' href='http://raciocioniosespurios.blogspot.com/2012/01/encontro-com-os-editores.html' title='Encontro com os editores'/><author><name>Márcio Laurini</name><uri>http://www.blogger.com/profile/04390359930936234810</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-26274345.post-4192836522143710487</id><published>2012-01-05T23:46:00.002-02:00</published><updated>2012-01-05T23:58:40.908-02:00</updated><title type='text'>O melhor gerador de números aleatórios já construído</title><content type='html'>Geração de números aleatórios é um tema fundamental em análise numérica, e existem inúmeras referências e métodos disponíveis.

Em especial foi um ano relativamente tranquilo, se comparado aos anos anteriores. E isso é bom.&lt;br /&gt;Consegui trabalhar bastante, e com a diferença que consegui investir um pesquisas de mais longo prazo. E o principal, foi um ano de muito aprendizado, o que sempre foi meu objetivo fundamental.&lt;br /&gt;Alguns projetos deram muito mais trabalho que  o planejado (ainda estão dando), mas acho que mesmo essas dificuldades foram muito úteis, já que para resolver os problemas que surgiram precisei aprender várias técnicas novas.  Ainda ficou muita coisa pendente para 2012, mas felizmente só pontos finais.&lt;br /&gt;&lt;br /&gt;E o lema do ano, do grande pensador Rocky Balboa:&lt;br /&gt;&lt;br /&gt;"But it ain't about how hard ya hit. It's about how hard you can get it  and keep moving forward. How much you can take and keep moving forward.  That's how winning is done!

Many modern statistical applications involve inference for complex stochastic models, where it is easy to simulate from the models, but impossible to calculate likelihoods.Approximate Bayesian computation (ABC) is a method of inference for such models. It replaces calculation of the likelihood by a step which involves simulating artificial data for different parameter values, and comparing summary statistics of the simulated data with summary statistics of the observed data. Here we show how to construct appropriate summary statistics for ABC in a semi-automatic manner.We aim for summary statistics which will enable inference about certain parameters of interest to be as accurate as possible. Theoretical results show that optimal summary statistics are the posterior means of the parameters. Although these cannot be calculated analytically, we use an extra stage of simulation to estimate how the posterior means vary as a function of the data; and we then use these estimates of our summary statistics within ABC. Empirical results show that our approach is a robust method for choosing summary statistics that can result in substantially more accurate ABC analyses than the ad hoc choices of summary statistics that have been proposed in the literature.We also demonstrate advantages over two alternative methods of simulation-based inference. &lt;/a&gt;&lt;/div&gt;&lt;div&gt;&lt;a href="http://www.rss.org.uk/uploadedfiles/userfiles/files/Fearnhead_Dec__14.pdf"&gt;Keywords: Indirect inference; Likelihood-free inference; Markov chain Monte Carlo methods;&lt;/a&gt;&lt;/div&gt;&lt;div&gt;&lt;a href="http://www.rss.org.uk/uploadedfiles/userfiles/files/Fearnhead_Dec__14.pdf"&gt;Simulation; Stochastic kinetic networks&lt;/a&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/26274345-7922653337964938740?l=raciocioniosespurios.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://raciocioniosespurios.blogspot.com/feeds/7922653337964938740/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=26274345&amp;postID=7922653337964938740&amp;isPopup=true' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/7922653337964938740'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/7922653337964938740'/><link rel='alternate' type='text/html' href='http://raciocioniosespurios.blogspot.com/2011/12/leitura-do-dia-constructing-summary.html' title='Leitura do Dia - Constructing summary statistics for approximate Bayesian computation: semi-automatic approximate Bayesian computation'/><author><name>Márcio Laurini</name><uri>http://www.blogger.com/profile/04390359930936234810</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-26274345.post-8958475534880437865</id><published>2011-12-12T22:08:00.002-02:00</published><updated>2011-12-12T22:38:24.121-02:00</updated><title type='text'>SBE 2011</title><content type='html'>Uma breve lista das minhas impressões sobre o Encontro de Econometria deste ano. A primeira é que o encontro manteve o padrão de excelente organização dos anos passados, e tudo ocorreu sem problemas, mantendo o padrão. &lt;div&gt;Como aproveitei para trabalhar em alguns artigos, não vi muitas sessões. Assisti a sessão de Retornos Financeiros e Volatilidade, e gostei muito das apresentação do Osvaldo sobre cópulas, e foi bom ver novamente a do Eduardo sobre analise funcional de dados. Também assisti a sessão Política Monetária II, e achei as apresentações do Rodrigo, do Raphael e do Henrique Basso realmente muito interessantes. A outra sessão que assisti parcialmente foi a de política fiscal, e apenas vi a apresentação do Fiorêncio, que é sempre um bom e claro apresentador. &lt;/div&gt;&lt;div&gt;A sessão especial sobre finanças corporativas teve apresentações de dois dos maiores pesquisadores nesse assunto - Gustavo Manso e Daniel Ferreira, e as apresentações honraram o nível esperado. Eu gosto particularmente das pesquisas do Gustavo, unindo uma abordagem técnica muito sofisticada a uma intuição acurada, e acho que sua abordagem sobre feedback effects in ratings é a referência fundamental nesse assunto. &lt;/div&gt;&lt;div&gt;Eu gostei bastante das duas sessões que eu participei. Na de estrutura a termo existia uma proximidade grande entre as apresentações, o que ajudava bastante na discussão. Eu acho que o outro artigo que eu apresentei sobre modelos não-paramétricos seria mais apropriado nesta sessão, mas de qualquer forma aprendi bastante nessa sessão. &lt;/div&gt;&lt;div&gt;Na sessão de métodos econométricos, pude apresentar com bastante calma meu artigo sobre uma abordagem não-paramétrica para curvas no tempo, e isso foi bastante gratificante já que é um artigo que eu gosto bastante. Mas o ponto alto foi a apresentação do Prof. Valdério sobre estimadores robustos em métodos espectrais, que foi uma brilhante aula sobre este tema. &lt;/div&gt;&lt;div&gt;Senti falta de mais artigos sobre teoria econométrica, mas isso é um reflexo dos temas de pesquisa de destaque atuais.  Mas como fiquei trabalhando em várias sessões posso ter perdido algumas apresentações relacionadas. &lt;/div&gt;&lt;div&gt;Encontrei muitos e muitos amigos, e acho que neste aspecto o encontro desse ano teve um clima muito bom mesmo. &lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/26274345-8958475534880437865?l=raciocioniosespurios.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://raciocioniosespurios.blogspot.com/feeds/8958475534880437865/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=26274345&amp;postID=8958475534880437865&amp;isPopup=true' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/8958475534880437865'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/8958475534880437865'/><link rel='alternate' type='text/html' href='http://raciocioniosespurios.blogspot.com/2011/12/sbe-2011.html' title='SBE 2011'/><author><name>Márcio Laurini</name><uri>http://www.blogger.com/profile/04390359930936234810</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-26274345.post-2631007115832390719</id><published>2011-12-12T11:16:00.002-02:00</published><updated>2011-12-12T11:22:15.076-02:00</updated><title type='text'>Brazilian Review of Econometrics - Special Volume in Honor of Ricardo Paes de Barros</title><content type='html'>&lt;a href="http://bibliotecadigital.fgv.br/ojs/index.php/bre/issue/view/Special%20Volume"&gt;Vol 30, No 2 (2010): Special Volume in Honor of Ricardo Paes de Barros&lt;br /&gt;&lt;/a&gt;&lt;br /&gt;&lt;a href="http://bibliotecadigital.fgv.br/ojs/index.php/bre/issue/view/Special%20Volume"&gt;Table of Contents&lt;br /&gt;Comments&lt;br /&gt;&lt;br /&gt;INTRODUCTION by James Heckman (University of Chicago and American Bar Foundation)  PDF&lt;br /&gt;James J.

Para uma idéia, no primeiro protótipo que eu montei, com uma estrutura mais simples, cada iteração de MCMC levava cerca de 6 segundos.&lt;br /&gt;Se funcionar acho que terei alguns resultados interessantes para comentar.&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/26274345-4066382415569402508?l=raciocioniosespurios.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://raciocioniosespurios.blogspot.com/feeds/4066382415569402508/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=26274345&amp;postID=4066382415569402508&amp;isPopup=true' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/4066382415569402508'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/4066382415569402508'/><link rel='alternate' type='text/html' href='http://raciocioniosespurios.blogspot.com/2011/11/final-frontier.html' title='The final frontier'/><author><name>Márcio Laurini</name><uri>http://www.blogger.com/profile/04390359930936234810</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-26274345.post-3286455980301155303</id><published>2011-11-15T13:08:00.003-02:00</published><updated>2011-11-15T13:13:36.030-02:00</updated><title type='text'>Feriado</title><content type='html'>&lt;a href="http://3.bp.blogspot.com/-bhU0FOH_fSE/TsKAq8bXIEI/AAAAAAAABNo/t1fRJMFQMQE/s1600/phi1.jpg" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"&gt;&lt;img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 400px; height: 283px;" src="http://3.bp.blogspot.com/-bhU0FOH_fSE/TsKAq8bXIEI/AAAAAAAABNo/t1fRJMFQMQE/s400/phi1.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5675239955703996482" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;Como é uma insanidade total viajar do/para o Rio durante um feriado, a melhor opção é aproveitar e colocar a pesquisa em dia.

Competing banks prefer to pay their banking sta  in bonuses and not in  fixed&lt;br /&gt;wages as risk sharing on the remuneration bill is valuable. Competition for bankers generates a&lt;br /&gt;negative externality driving up market levels of banker remuneration and so rival banks' default&lt;br /&gt;risk. Optimal  nancial regulation involves an appropriately structured limit on the proportion of&lt;br /&gt;the balance sheet used for bonuses. However stringent bonus caps are value destroying, default&lt;br /&gt;risk enhancing and cannot be optimal for regulators who control only a small number of banks.&lt;br /&gt;Keywords: Bonuses, default risk, competition for bankers, fi nancial regulation.&lt;br /&gt;JEL Classi cation: G21, G34.&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;Recentemente &lt;a href="http://www.nytimes.com/2011/11/08/opinion/end-bonuses-for-bankers.html?_r=2"&gt;Nassim Taleb propos o fim do pagamento de bônus no setor financeiro como forma de evitar crises bancárias&lt;/a&gt;. Como a maioria das análises do Taleb, é baseada em puro sentimento e pouca análise.  O artigo acima, a sair no Journal of Finance, mostra que esta decisão é bem mais complexa.&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1'

You believe nothing will ever change. Then you leave: a year, two years. When you come back, everything's changed. The thread's broken. What you came to find isn't there. What was yours is gone. You have to go away for a long time... many years... before you can come back and find your people. The land where you were born. But now, no. It's not possible. Right now you're blinder than I am."&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;A versão que foi mostrada era a a versão internacional, e não a do diretor, que é mais complexa e triste.

Existe uma conexão dessa para o matlab, e o eviews a partir da versão 7 também tem uma conexão com o R.&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/26274345-6744831481117422557?l=raciocioniosespurios.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://raciocioniosespurios.blogspot.com/feeds/6744831481117422557/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=26274345&amp;postID=6744831481117422557&amp;isPopup=true' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/6744831481117422557'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/6744831481117422557'/><link rel='alternate' type='text/html' href='http://raciocioniosespurios.blogspot.com/2011/10/rexcel.html' title='Rexcel'/><author><name>Márcio Laurini</name><uri>http://www.blogger.com/profile/04390359930936234810</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-26274345.post-5916159510066067967</id><published>2011-10-23T12:33:00.001-02:00</published><updated>2011-10-23T12:35:42.205-02:00</updated><title type='text'>Pega Ma Beibe</title><content type='html'>&lt;iframe width="560" height="315" src="http://www.youtube.com/embed/fag6n_W8Zs4" frameborder="0" allowfullscreen=""&gt;&lt;/iframe&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;Para comemorar o belo dia aqui Rj.&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/26274345-5916159510066067967?l=raciocioniosespurios.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://raciocioniosespurios.blogspot.com/feeds/5916159510066067967/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=26274345&amp;postID=5916159510066067967&amp;isPopup=true' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/5916159510066067967'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/5916159510066067967'/><link rel='alternate' type='text/html' href='http://raciocioniosespurios.blogspot.com/2011/10/pega-ma-beibe.html' title='Pega Ma Beibe'/><author><name>Márcio Laurini</name><uri>http://www.blogger.com/profile/04390359930936234810</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://img.youtube.com/vi/fag6n_W8Zs4/default.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-26274345.post-2121386672733339348</id><published>2011-10-22T00:37:00.003-02:00</published><updated>2011-10-22T00:43:26.552-02:00</updated><title type='text'>Novas Aquisições - Continuous-Time Finance</title><content type='html'>&lt;a href="http://1.bp.blogspot.com/-27WgMbsH-94/TqIsv_OBR6I/AAAAAAAABME/odQ72aBMnPQ/s1600/merton.jpg" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"&gt;&lt;img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 168px; height: 262px;" src="http://1.bp.blogspot.com/-27WgMbsH-94/TqIsv_OBR6I/AAAAAAAABME/odQ72aBMnPQ/s400/merton.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5666140484121216930" /&gt;&lt;/a&gt;Continous-Time Finance - Robert Merton&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;Como eu não tinha o clássico livro do Merton, acabei comprando uma cópia usada na Amazon.

Ficou mais simples de usar que meu sistema antigo em Perl, e por isso deve ser mais útil para os alunos. &lt;/div&gt;&lt;div&gt;Na figura a construção de uma curva a partir dos dados de DI1, e usando a visualização 3d usando RGL (não é muito clara, mas é bem divertida).

Mas uma que foi mágica foi a lembrança de um álbum de figurinhas de ficção científica que tive aos 8 anos de idade, o álbum S.P.A.C.E - &lt;meta equiv="content-type" content="text/html; charset=utf-8"&gt;&lt;span class="Apple-style-span" style="color: rgb(34, 34, 34); font-family: Georgia, Utopia, 'Palatino Linotype', Palatino, serif; font-size: 15px; line-height: 21px; "&gt;&lt;i&gt; Sistemas e Planos de Ataque a Comandos Estelares.&lt;/i&gt;&lt;/span&gt; Não lembrava do nome do álbum, mas lembrava de cada figura e especialmente do texto que acompanhava cada uma. &lt;div&gt;Mas a grande surpresa &lt;a href="http://mensagensdohiperespaco.blogspot.com/2009/11/space.html"&gt;foi descobrir que existe um texto excelente sobre o S.P.A.C.E, e mais ainda  uma versão em pdf do álbum completo&lt;/a&gt;, e foi um prazer enorme reler tudo. Obviamente naquela época não percebi, mas agora depois de centenas de livros de ficção científica é possível ver todas as referẽncias que estão no álbum, não só as que o álbum provavelmente influenciou (como as citadas no link sobre &lt;span class="Apple-style-span" style="color: rgb(34, 34, 34); font-family: Georgia, Utopia, 'Palatino Linotype', Palatino, serif; font-size: 15px; line-height: 21px; "&gt;&lt;i&gt;A ameaça fantasma&lt;/i&gt;, &lt;i&gt;O ataque dos clones&lt;/i&gt; e a&lt;i&gt;Vingança dos &lt;/i&gt;&lt;i&gt;Sith),&lt;/i&gt;&lt;/span&gt;&lt;/div&gt;&lt;meta equiv="content-type" content="text/html; charset=utf-8"&gt;, mas também sobre as que influenciaram o próprio álbum.

Wood&lt;/a&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;Eu já utilizava com frequência o pacote mgcv do Simon Wood, que é um dos melhores pacotes do R. E como precisei modificar algumas funções do pacote, também já havia visto a eficiência das implementações dele (o algoritmo de estimação por outer iteration é especialmente bonito e eficaz).  Mas apesar dessa boa impressão, o livro do Wood é ainda melhor.  Além da introdução a teoria e a aplicações de modelos aditivos (splines, tensor splines, thin plate, penalized splines, etc) o livro ainda tem dois capitulos excelentes sobre modelos lineares e sobre modelos lineares generalizados (GLM).  O capítulo sobre modelos lineares é bem interessante já que deriva as propriedades do estimador linear usando a decomposição QR, que é o método computacional usual para estimação de modelos lineares. Ele também apresenta a forma normal, mas o uso da decomposição QR é bem interessante para obter as propriedades teóricas. &lt;/div&gt;&lt;div&gt;Os demais capítulos sobre modelos aditivos formam uma das melhores referências sobre o assunto, e fazem um par perfeito para um livro mais teórico como o Spline Models for Observational Data da Grace Wahba. Também há um capítulo sobre modelos lineares mistos e suas generalizações (linear mixed models e generalized linear mixed models). &lt;/div&gt;&lt;div&gt;E o livro, como prometido, é repleto de ilustrações usando o R. E mais ainda, é muito bem escrito, e com um tom divertido, como  na introdução:&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;"Life is to short to spend too much of it reading statistics texts. This book is of course an exception to this rule and should be read to cover to cover ..."&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;Excelente aquisição. &lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/26274345-3859866030165421653?l=raciocioniosespurios.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://raciocioniosespurios.blogspot.com/feeds/3859866030165421653/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=26274345&amp;postID=3859866030165421653&amp;isPopup=true' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/3859866030165421653'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/3859866030165421653'/><link rel='alternate' type='text/html' href='http://raciocioniosespurios.blogspot.com/2011/10/novas-aquisicoes-generalized-additive.html' title='Novas Aquisições - Generalized Additive Models'/><author><name>Márcio Laurini</name><uri>http://www.blogger.com/profile/04390359930936234810</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://3.bp.blogspot.com/-TkVin5wHrqU/TpZZvyWTYtI/AAAAAAAABLg/EJSwxOoNG6A/s72-c/mgcv.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-26274345.post-1057687921089844789</id><published>2011-10-12T09:27:00.002-03:00</published><updated>2011-10-12T09:49:13.296-03:00</updated><title type='text'>Math is the language of economics</title><content type='html'>Do site do Thomas Sargent uma recomendação fundamental:&lt;br /&gt;&lt;br /&gt;&lt;a href="https://files.nyu.edu/ts43/public/math_courses.html"&gt;Math is the language of economics.  If you are an NYU undergraduate, studying math will open doors to you in terms of interesting economics courses at NYU and  job opportunities afterwards.  Start with the basics: take three calculus courses (up to and including multivariable calculus), linear algebra, and a good course in probability and statistics.  These basic courses will empower you.  After you have these under your belt, you have many interesting options all of which will further empower you to learn and practice economics.  I especially recommend courses in (1) Markov chains and stochastic processes, and (2) differential equations.&lt;br /&gt;&lt;br /&gt;Superb economists at NYU (e.g., Adam Brandenburger, Robert Engle, Roy Radner, Stanley Zin, Jess Benhabib, Douglas Gale, Boyan Jovanovic, David Pearce, Debraj Ray,  Ennio Stacchetti, Charles Wilson, and others) have made notable contributions to economics partly because they are creative but also because they studied more math than others. &lt;/a&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;Ele também faz uma lista dos cursos sugeridos para um track de matemática, &lt;a href="https://files.nyu.edu/ts43/public/math_courses_NYU.html"&gt;na NYU&lt;/a&gt; e &lt;a href="https://files.nyu.edu/ts43/public/math_courses_Stanford.html"&gt;em Stanford&lt;/a&gt;.  A lista da NYU é mais completa, e tem uma série de cursos de métodos numéricos, e também uma série de cursos de probabilidade. &lt;/div&gt;&lt;div&gt;A boa notícia é um aluno de economia de uma grande universidade brasileira pode criar um track muito parecido com esse, já que a maioria dos cursos faz parte das formações básicas em matemática, estatística e computação. &lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/26274345-1057687921089844789?l=raciocioniosespurios.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://raciocioniosespurios.blogspot.com/feeds/1057687921089844789/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=26274345&amp;postID=1057687921089844789&amp;isPopup=true' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/1057687921089844789'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/1057687921089844789'/><link rel='alternate' type='text/html' href='http://raciocioniosespurios.blogspot.com/2011/10/math-is-language-of-economics.html' title='Math is the language of economics'/><author><name>Márcio Laurini</name><uri>http://www.blogger.com/profile/04390359930936234810</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-26274345.post-3425092566182485757</id><published>2011-10-12T00:52:00.000-03:00</published><updated>2011-10-12T00:54:24.465-03:00</updated><title type='text'></title><content type='html'>'ve changed my ways a little; I cannot now &lt;br /&gt;Run with you in the evenings along the shore, &lt;br /&gt;Except in a kind of dream; and you, if you dream a moment, &lt;br /&gt;You see me there. &lt;br /&gt;&lt;br /&gt;So leave awhile the paw-marks on the front door &lt;br /&gt;Where I used to scratch to go out or in, &lt;br /&gt;And you'd soon open; leave on the kitchen floor &lt;br /&gt;The marks of my drinking-pan. &lt;br /&gt;&lt;br /&gt;I cannot lie by your fire as I used to do &lt;br /&gt;On the warm stone, &lt;br /&gt;Nor at the foot of your bed; no, all the night through &lt;br /&gt;I lie alone. &lt;br /&gt;&lt;br /&gt;But your kind thought has laid me less than six feet &lt;br /&gt;Outside your window where firelight so often plays, &lt;br /&gt;And where you sit to read--and I fear often grieving for me-- &lt;br /&gt;Every night your lamplight lies on my place. &lt;br /&gt;&lt;br /&gt;You, man and woman, live so long, it is hard &lt;br /&gt;To think of you ever dying &lt;br /&gt;A little dog would get tired, living so long. &lt;br /&gt;I hope than when you are lying &lt;br /&gt;&lt;br /&gt;Under the ground like me your lives will appear &lt;br /&gt;As good and joyful as mine. &lt;br /&gt;No, dear, that's too much hope: you are not so well cared for &lt;br /&gt;As I have been. &lt;br /&gt;&lt;br /&gt;And never have known the passionate undivided &lt;br /&gt;Fidelities that I knew. &lt;br /&gt;Your minds are perhaps too active, too many-sided. . . . &lt;br /&gt;But to me you were true. &lt;br /&gt;&lt;br /&gt;You were never masters, but friends.

Está ainda completo, mas é muito interessante.  Em especial ele comenta sobre alguns métodos clássicos que ainda não tem uma correspondência completa* em termos Bayesianos, como GMM, Variáveis Instrumentais e Métodos Não-Paramétricos.&lt;br /&gt;&lt;br /&gt;&lt;a href="http://sims.princeton.edu/yftp/UndrstndgNnBsns/GewekeBookChpter.pdf"&gt;Introduction&lt;br /&gt;&lt;br /&gt;Once one becomes used to thinking about inference from a Bayesian perspective, it becomes difficult to understand why many econometricians are uncomfortable with that way of thinking. But some very good econometricians are either firmly non- Bayesian or (more commonly these days) think of Bayesian approaches as a “tool” which might sometimes be appropriate, sometimes not. This paper tries to articulate the counterarguments to a Bayesian perspective. There are some counterarguments that are frequently expressed, but are not hard to dismiss. Others, though, correspond to types of application where convenient, seemingly sensible, frequentist tools exist, while Bayesian approaches are either not yet developed or seem quite inconvenient. And there are also counterarguments that relate to deep questions about inference on infinite-dimensional parameter spaces and to corresponding pitfalls in the application of Bayesian ideas. Section II explains the difference between Bayesian and frequentist approaches to inference. Section III discusses commonly heard, but weak, objections, while section IV takes up subtler issues. Section V illustrates the subtler issues in the context of some specific models.&lt;br /&gt;To relieve the reader’s possible suspense: My conclusion is that the Bayesian perspective is indeed universally applicable, but that “non-parametric” inference is hard, in ways about which both Bayesians and non-Bayesians are sometimes careless.&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;* - Na verdade existem várias formalizações de estimações Bayesianos de  Momentos, Variáveis Instrumentais e diversas formas de métodos  Bayesianos não-paramétricos, mas creio que ainda não exista uma forma  consolidada de tratar destas metodologias.

Lynyrd Skynyrd, Creedence Clearwater Revival ... e ainda hoje temos o Gov't Mule e Derek Trucks Band mandando ver de verdade. &lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/26274345-373660409745052336?l=raciocioniosespurios.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://raciocioniosespurios.blogspot.com/feeds/373660409745052336/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=26274345&amp;postID=373660409745052336&amp;isPopup=true' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/373660409745052336'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/373660409745052336'/><link rel='alternate' type='text/html' href='http://raciocioniosespurios.blogspot.com/2011/10/free-bird.html' title='Free Bird'/><author><name>Márcio Laurini</name><uri>http://www.blogger.com/profile/04390359930936234810</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://img.youtube.com/vi/np0solnL1XY/default.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-26274345.post-4616807148764254344</id><published>2011-10-06T12:10:00.000-03:00</published><updated>2011-10-06T12:11:15.862-03:00</updated><title type='text'>Bert Jansch</title><content type='html'>&lt;iframe width="420" height="315" src="http://www.youtube.com/embed/RqjUWJtH88c" frameborder="0" allowfullscreen=""&gt;&lt;/iframe&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;Bert Jansch +.  &lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/26274345-4616807148764254344?l=raciocioniosespurios.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://raciocioniosespurios.blogspot.com/feeds/4616807148764254344/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=26274345&amp;postID=4616807148764254344&amp;isPopup=true' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/4616807148764254344'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/4616807148764254344'/><link rel='alternate' type='text/html' href='http://raciocioniosespurios.blogspot.com/2011/10/bert-jansch.html' title='Bert Jansch'/><author><name>Márcio Laurini</name><uri>http://www.blogger.com/profile/04390359930936234810</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://img.youtube.com/vi/RqjUWJtH88c/default.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-26274345.post-1876551271810496523</id><published>2011-10-05T22:33:00.001-03:00</published><updated>2011-10-05T22:36:09.648-03:00</updated><title type='text'>Adeus, Jobs.</title><content type='html'>Morre Steve Jobs.

Were an opinion a personal possession of no value except to the owner; if to be obstructed in the enjoyment of it were simply a private injury, it would make some difference whether the injury was inflicted only on a few persons or on many. But the peculiar evil of silencing the expression of an opinion is, that it is robbing the human race; posterity as well as the existing generation; those who dissent from the opinion, still more than those who hold it. If the opinion is right, they are deprived of the opportunity of exchanging error for truth: if wrong, they lose, what is almost as great a benefit, the clearer perception and livelier impression of truth, produced by its collision with error. &lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt; On Liberty, John Stuart Mill&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/26274345-2794584497555901586?l=raciocioniosespurios.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://raciocioniosespurios.blogspot.com/feeds/2794584497555901586/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=26274345&amp;postID=2794584497555901586&amp;isPopup=true' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/2794584497555901586'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/2794584497555901586'/><link rel='alternate' type='text/html' href='http://raciocioniosespurios.blogspot.com/2011/09/on-liberty.html' title='On Liberty'/><author><name>Márcio Laurini</name><uri>http://www.blogger.com/profile/04390359930936234810</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-26274345.post-3964174251745063203</id><published>2011-09-30T01:02:00.002-03:00</published><updated>2011-09-30T01:13:41.639-03:00</updated><title type='text'>Pesadelos numéricos II</title><content type='html'>Normalmente eu rodo meus programas em R no meu laptop (dual boot com linux e windows), e nos computadores no Ibmec usando windows.  Uma vantagem de rodar em Linux é que as bibliotecas podem ser compiladas do código fonte de uma forma bem natural, enquanto que no windows é preciso usar o mingw, instalar r-tools, instalar algumas bibliotecas manualmente, etc.  Não é difícil, mas é mais trabalhoso.&lt;div&gt;Mas algo muito irritante no windows é que muitas estruturas de controle de erro não funcionam da forma adequada. &lt;/div&gt;&lt;div&gt;Por exemplo no windows se eu chamo um executável externo pelo R, e ocorre algum erro de execução que leva a finalização do programa, em muitos casos o windows abre uma janela informando que o programa foi finalizado, e pede para o usuário confirmar pressionando um botão.  Evidentemente isso em geral é bastante inadequado, já que se eu estou utilizando controle de erro no R (por exemplo utilizando try e try-catch), eu quero manter meu programa funcionando mesmo na possibilidade de algum erro de execução. Por exemplo o tratamento de erro em uma simulação de monte carlo seria descartar a iteração onde ocorre um erro e continuar com as demais execuções. &lt;/div&gt;&lt;div&gt;Dessa forma seria interessante evitar essa janela de erro. Já tentei fazer isso de várias formas, mudando opções no windows, tentando mudar os códigos fonte, etc, mas nada resolve esse maldito comportamento.&lt;/div&gt;&lt;div&gt;Se alguém souber de alguma forma de evitar esse comportamento eu seria muito grato.  &lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/26274345-3964174251745063203?l=raciocioniosespurios.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://raciocioniosespurios.blogspot.com/feeds/3964174251745063203/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=26274345&amp;postID=3964174251745063203&amp;isPopup=true' title='2 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/3964174251745063203'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/3964174251745063203'/><link rel='alternate' type='text/html' href='http://raciocioniosespurios.blogspot.com/2011/09/pesadelos-numericos-ii.html' title='Pesadelos numéricos II'/><author><name>Márcio Laurini</name><uri>http://www.blogger.com/profile/04390359930936234810</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>2</thr:total></entry><entry><id>tag:blogger.com,1999:blog-26274345.post-6923800172751133477</id><published>2011-09-29T17:27:00.002-03:00</published><updated>2011-09-29T17:56:49.920-03:00</updated><title type='text'>Pesadelos numéricos</title><content type='html'>Noites de pouco sono devido a dois pesadelos numéricos. O primeiro está na reimplementação das minhas rotinas de verossimilhança empírica usando bibliotecas de multipla precisão numérica. Em algumas partes as modificações foram fáceis, mas em algumas surgem alguns problemas bem complicados. Outro problema é que com precisão alta (128 bits) por exemplo, a estimação fica muito mais lenta.  Mas até agora os resultados foram bons. &lt;div&gt;O segundo problema está na minha parametrização de modelos SV usando INLA. A formulação standard desses modelos assume estacionaridade e apenas priors gaussianas para a persistência. Precisei reparametrizar totalmente o modelo SV no INLA para retirar essas restrições, mas ainda existem alguns problemas numéricos complicados, e precisei modificar várias partes dos códigos fonte do INLA para obter um resultado confiável, mas para algumas simulações os resultados não estão de acordo com o que eu esperava. Lentamente vou resolvendo os problemas, mas está demorando mais tempo que o previsto. &lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/26274345-6923800172751133477?l=raciocioniosespurios.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://raciocioniosespurios.blogspot.com/feeds/6923800172751133477/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=26274345&amp;postID=6923800172751133477&amp;isPopup=true' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/6923800172751133477'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/6923800172751133477'/><link rel='alternate' type='text/html' href='http://raciocioniosespurios.blogspot.com/2011/09/pesadelos-numericos.html' title='Pesadelos numéricos'/><author><name>Márcio Laurini</name><uri>http://www.blogger.com/profile/04390359930936234810</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-26274345.post-6418846527119459631</id><published>2011-09-28T11:25:00.002-03:00</published><updated>2011-09-28T11:33:11.859-03:00</updated><title type='text'>20 anos sem Miles Davis</title><content type='html'>&lt;iframe width="420" height="315" src="http://www.youtube.com/embed/KrmQwreKssw" frameborder="0" allowfullscreen=""&gt;&lt;/iframe&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;20 anos sem Miles Davis, o músico que revolucionou a música várias e várias vezes.

Métodos de regularização são aplicados para resolver  problemas (muito comuns) de condicionamento de matrizes que surgem nessas duas literaturas, e são normalmente resolvidos através de penalizações nas funções objetivo. O exemplo mais simples desse problema em econometria é a técnica conhecida como Ridge Regression.&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;Duas referências muito úteis nesse assunto são essa coleção de materiais da Marine Carrasco:&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;a href="https://www.webdepot.umontreal.ca/Usagers/carrascm/MonDepotPublic/carrascm/inverse/"&gt;Inverse Problems in Econometrics: An Annotated Bibliography &lt;/a&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;e a documentação e a toolbox em matlab sobre regularização:&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;a href="http://www2.imm.dtu.dk/~pch/Regutools/"&gt;Regularization Tools&lt;/a&gt; do &lt;span class="Apple-style-span" style="font-family: 'Times New Roman'; font-size: medium; "&gt;&lt;a href="http://www.imm.dtu.dk/~pch"&gt;Prof. Per Christian Hansen&lt;/a&gt;. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span class="Apple-style-span" style="font-family: 'Times New Roman'; font-size: medium; "&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span class="Apple-style-span" style="font-family: 'Times New Roman'; font-size: medium; "&gt;Mas para reforçar - uma coleção de resultados fundamentais sobre regularização pode ser encontrada nos trabalhos da Grace Wahba (&lt;a href="http://raciocioniosespurios.blogspot.com/2011/09/origem.html"&gt;como colocado post anterior&lt;/a&gt;), e o resultado fundamental é que basicamente cada problema de regularização pode ser escrito como um problema de estimação por smoothing splines.  &lt;/span&gt;&lt;/div&gt;&lt;meta equiv="content-type" content="text/html; charset=utf-8"&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/26274345-1170134980047988224?l=raciocioniosespurios.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://raciocioniosespurios.blogspot.com/feeds/1170134980047988224/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=26274345&amp;postID=1170134980047988224&amp;isPopup=true' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/1170134980047988224'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/26274345/posts/default/1170134980047988224'/><link rel='alternate' type='text/html' href='http://raciocioniosespurios.blogspot.com/2011/09/regularizacao.html' title='Regularização'/><author><name>Márcio Laurini</name><uri>http://www.blogger.com/profile/04390359930936234810</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry></feed>
