Inferência bayesiana para o tamanho de uma população fechada com erros de registros de dados amostrais
(Universidade Federal de São Carlos, 2008-06-12)
In this dissertation we determine maximum likelihood and bayesian estimates of the size of a closed population, from two lists of data of elements of the population. It has been supposed that the registers of the individual ...
Modelo de mistura padrão com tempos de vida exponenciais ponderados
(Universidade Federal de São Carlos, 2010-03-05)
In this work, we brie_y introduce the concepts of long-term survival analysis. We dedicated ourselves exclusively to the standard mixture cure model from Boag (1949) and Berkson & Gage (1952), showing its deduction and ...
Um modelo de risco proporcional dependente do tempo
(Universidade Federal de São Carlos, 2007-03-30)
Survival data analysis models is used to study experimental data where, normally,
the variable "answer"is the time passed until an event of interest. Many authors do prefer
modeling survival data, in the presence of ...
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 ...
