Um método para construção de distribuições de probabilidades do tipo contínuo
(Universidade Federal de São Carlos, 2013-05-10)
Modelos para dados de sobrevivência na presença de diferentes esquemas de ativação baseados na distribuição geométrica
(Universidade Federal de São Carlos, 2013-04-08)
In this thesis new families of survival distributions are proposed. Those distributions are derived by assuming a latent activation structure to explain the occurrence of the event of interest. In general, the competitive ...
Modelos de regressão bivariados Bernoulli : exponencial
(Universidade Federal de São Carlos, 2013-04-05)
Aspectos práticos da estimação do modelo de mistura via processo de Dirichlet
(Universidade Federal de São Carlos, 2013-04-03)
We review the Dirichlet process mixture model and investigate its performance as a classification method. The first aspect considered is its sensibility to the choice of location parameter of the base distribution. The ...
Uma família de modelos de regressão com a distribuição original da variável resposta
(Universidade Federal de São Carlos, 2013-04-05)
We know that statistic modeling by regression had a stronger impulse since generalized linear models (GLMs) development in 70 decade beginning of the XX century, proposed by Nelder e Wedderburn (1972). GLMs theory can be ...
Análise da qualidade do ar : um estudo de séries temporais para dados de contagem
(Universidade Federal de São Carlos, 2013-04-30)
The aim of this study was to investigate the monthly amount of unfavourable days to pollutant dispersion in the atmosphere on the metropolitan region of S ão Paulo (RMSP). It was considered two data sets derived from the ...
Modelo de mistura paramétrico com fragilidade na presença de covariáveis
(Universidade Federal de São Carlos, 2013-04-23)
Some studies involving survival data are characterized by showing a significant proportion of censored data, that is, individuals who will never experience the event of interest, even if accompanied by a long period of ...
Inferência em distribuições discretas bivariadas
(Universidade Federal de São Carlos, 2013-11-26)
The analysis of bivariate data can be found in several areas of knowledge, when the data of interest are obtained in a paired way and present correlation between counts. In this work the Holgate bivariate Poisson, bivariate ...
Estimadores não paramétricos para dados com censura
(Universidade Federal de São Carlos, 2013-04-19)
In this paper we study the reliability of systems with connected components in series and parallel. For systems in series, the device fails when the first component fails. Although in the parallel systems this happens when ...
Análise estatística do modelo de Nelson e Siegel
(Universidade Federal de São Carlos, 2013-03-21)
The present paper studies the yield curve, an important tool for financial decisions, due to its fundamental role in the implementation and evaluation of monetary policies by the central banks. It also shows market ...
