Estimação Bayesiana do tamanho de uma população de diabéticos através de listas de pacientes
(Universidade Federal de São Carlos, 2005-02-25)
In this work, a bayesian methodology is shown to estimate the size of a diabethic-su¤ering population through lists containing information data of patients. The applied methodology is analogous of capture-recaptures in ...
Métodos de agrupamento na análise de dados de expressão gênica
(Universidade Federal de São Carlos, 2009-02-16)
The clustering techniques have frequently been used in literature to the analyse data in several fields of application. The main objective of this work is to study such techniques. There is a large number of clustering ...

Aplicações de estatística em marketing
(Universidade Federal de São Carlos, 2007-12-14)
In this work, we analyse the use of the statistics in the improvement of some attitudes of a company regarding marketing strategy. We deal with methods which permit the identification of the best costumers and the preferences ...
Inferência bayesiana objetiva e freqüentista para a probabilidade de sucesso
(Universidade Federal de São Carlos, 2009-02-10)
This study considers two discrete distributions based on Bernoulli trials: the Binomial and the Negative Binomial. We explore credibility and confidence intervals to estimate the
probability of success of each distribution. ...
Abordagem clássica e bayesiana para os modelos de séries temporais da família GARMA com aplicações para dados contínuos
(Universidade Federal de São Carlos, 2011-03-24)
In this work, the aim was to analyze in the classic and bayesian context, the GARMA model with three different continuous distributions: Gaussian, Inverse Gaussian and Gamma. We analyzed the performance and the goodness ...
Dados de sobrevivência multivariados na presença de covariáveis e observações censuradas: uma abordagem bayesiana
(Universidade Federal de São Carlos, 2010-03-04)
In this work, we introduce a Bayesian Analysis for survival multivariate data in the presence of a covariate vector and censored observations. Different frailties or latent variables are considered to capture the correlation ...
Modelo de mistura com número de componentes desconhecido: estimação via método split-merge
(Universidade Federal de São Carlos, 2009-11-30)
We propose the split-merge MCMC and birth-split-merge MCMC algorithms to analyse mixture models with an unknown number of components. The strategy for splitting is based on data and posterior distribution. Allocation ...
Modelo de mistura padrão de longa duração com censura uniforme-exponencial
(Universidade Federal de São Carlos, 2010-03-25)
In survival data analysis it is common the occurrence of a large number of individuals to the right. This fact can indicate that, in a fraction of the individuals the event of interest will never happen, in other words, a ...
Classe de distribuições série de potências inflacionadas com aplicações
(Universidade Federal de São Carlos, 2009-04-06)
This work has as central theme the Inflated Modified Power Series Distributions, where the objective is to study its main properties and the applicability in the bayesian context. This class of models includes the generalized ...
