Função de intensidade Poisson perturbada pelo número de ocorrências para dados de eventos recorrentes
(Universidade Federal de São Carlos, 2007-06-22)
Uso de métodos clássicos e bayesianos em modelos de regressão beta
(Universidade Federal de São Carlos, 2007-05-18)
This work involves a study of a regression model appropriated for situations which the response variable is measured in a continuous scale in the (0, 1) interval, as, for instance, taxes or proportions. The developed ...
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 ...
Eliminação de parâmetros perturbadores na estimação de tamanhos populacionais
(Universidade Federal de São Carlos, 2010-01-15)
In this study, we used the capture-recapture procedure to estimate the size of a closed population. We analysed three di_erent statistics models. For each one of these models we determined - through several methods of ...
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 ...
Modelos de sobrevivência na presença de eventos recorrentes e longa duração
(Universidade Federal de São Carlos, 2010-03-05)
In this thesis it is proposed to analyze recurrent event data, recurrent event data with cure fraction and recurrent event data with censoring and competing causes. For the recurrent event data analysis it is proposed a ...
Uma análise bayesiana para dados composicionais.
(Universidade Federal de São Carlos, 2005-03-03)
Compositional data are given by vectors of positive numbers with sum equals to one.
These kinds of data are common in many applications, as in geology, biology, economy
among many others. In this paper, we introduce a ...
Estimação do Value at Risk via enfoque bayesiano
(Universidade Federal de São Carlos, 2007-01-26)
The continuous development of new financial instruments brings more and more
investment options for market participants. These investment options also bring a bigger
necessity to evaluate the risk embedded in these new ...
Modelos de séries temporais com coeficientes variando no tempo
(Universidade Federal de São Carlos, 2009-02-26)
In this work they are presented extensions of Auto Regressive and Auto Regressive Conditional Heteroscedasticity models with coefficients varying in time. These coefficients have
been used as models for non stationary real ...
