Modelos série de potência com excesso de zeros observáveis e latentes 

Coaguila Zavaleta, Katherine Elizabeth (Universidade Federal de São Carlos, 2016-09-28)
The present work's main objective is to study the significance of zeros in an observable and latent data. In observable data set that occur excess of zeros, its common to have sobredispersion. In this sense, the models ...

Modelos de sobrevivência com fração de cura via partição bayesiana 

Gonzales, Jhon Franky Bernedo (Universidade Federal de São Carlos, 2014-05-30)
In general, models for survival data with a cure fraction relate the cure fraction with the covariates using different link functions, for example, the logit link function and do not consider the problem of selection of ...

Modelo de mistura paramétrico com fragilidade na presença de covariáveis 

Taconeli, João Paulo (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 ...

Modelos de sobrevivência com base nas distribuições geométrica e exponencial 

Yamachi, Cíntia Yurie (Universidade Federal de São Carlos, 2013-02-01)
In this dissertation we propose four models to model lifetime data. The fist family of distribution is called Exponentiated Complementary Exponential Geometric distribution (ECEG) and it is obtained by exponentiation of ...

Extensões dos modelos de sobrevivência referente a distribuição Weibull 

Vigas, Valdemiro Piedade (Universidade Federal de São Carlos, 2014-03-07)
In this dissertation, two models of probability distributions for the lifetimes until the occurrence of the event produced by a specific cause for elements in a population are reviewed. The first revised model is called ...

Distribuição COM-Poisson na análise de dados de experimentos de quimioprevenção do câncer em animais 

Ribeiro, Angélica Maria Tortola (Universidade Federal de São Carlos, 2012-03-16)
Experiments involving chemical induction of carcinogens in animals are common in the biological area. Interest in these experiments is, in general, evaluating the chemopreventive effect of a substance in the destruction ...

Modelos de sobrevivência bivariados baseados na cópula FGM : uma abordagem bayesiana 

Suzuki, Adriano Kamimura (Universidade Federal de São Carlos, 2012-02-07)
In this work we present a Bayesian analysis for bivariate survival data in the presence of a covariate and censored observations. We propose a bivariate distribution for the bivariate survival times based on the ...

Modelos para dados de sobrevivência na presença de diferentes esquemas de ativação baseados na distribuição geométrica 

Roman, Mari (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 ...

Models for inflated data applied to credit risk analysis 

Oliveira Júnior, Mauro Ribeiro de (Universidade Federal de São Carlos, 2016-09-27)
In this thesis, we introduce a methodology based on zero-inflated survival data for the purposes of dealing with propensity to default (credit risk) in bank loan portfolios. Our approach enables us to accommodate three ...

Novas distribuições em análise de sobrevivência envolvendo composição e correlação dentre as causas competitivas 

Marchi, Vitor Alex Alves de (Universidade Federal de São Carlos, 2015-08-14)
In this thesis, we construct distribution functions for analysis of lifetimes with the focus in scenes of latent risks inspired in models of the carcinogenesis process. Some properties of these distribution functions are ...
