    • Parametric and semi-parametric cure rate models with spatial frailties for interval-censored data 

      Bao, Yiqi (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Estatística - PPGEs, Câmpus São Carlos, 31/05/2016)
      In this thesis, we extend some flexible cure rate models, such as the geometric, negative binomial and power series cure rate models, to allow for spatial correlations by including spatial frailties for the interval ...

    • Modelo alfa normal assimétrico multivariado para redes de classificação 

      Souza, Anderson Luiz Ara (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Estatística - PPGEs, Câmpus São Carlos, 16/03/2016)
      In this Thesis we expose the proposition of a new class of probability distributions, the so called alpha skew normal multivariate, an extension of the univariate Normal Alpha distribution, introduced by Elal-Olivero (2010). ...

    • Modelos para dados de contagem: um estudo sobre o número de ovos do mosquito Aedes aegypti 

      Nagamine, Camila Macedo Lima (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Estatística - PPGEs, , 22/07/2007)
      In this work we considered four types of models for count data: the Poisson model, the Negative Binomial Model and variations of these models for count inflated of zeros (ZIP and ZINB). Information on the number of put ...

    • Multivariate Copula-based SUR Tobit Models : a modified inference function for margins and interval estimation 

      Silva, Paulo Henrique Ferreira da (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Estatística - PPGEs, Câmpus São Carlos, 30/09/2015)
      In this thesis, we extend the analysis of multivariate Seemingly Unrelated Regression (SUR) Tobit models by modeling their nonlinear dependence structures through copulas. The capability in coupling together the diferent ...

    • Defective models for cure rate modeling 

      Rocha, Ricardo Ferreira da (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Estatística - PPGEs, Câmpus São Carlos, 01/04/2016)
      Modeling of a cure fraction, also known as long-term survivors, is a part of survival analysis. It studies cases where supposedly there are observations not susceptible to the event of interest. Such cases require special ...

    • Uma classe de modelos de regressão bivariados para respostas discreta e contínua 

      Oliveira, Willian Luís de (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Estatística - PPGEs, Câmpus São Carlos, 28/01/2016)
      In this thesis, a wide general class of models for mixed responses is proposed in which joint distributions are constructed by the conditional approach (probability density functions, (pdf), as the product of a marginal ...

    • Avaliação esportiva utilizando técnicas multivariadas: construção de indicadores e sistemas online 

      Maiorano, Alexandre Cristovão (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Estatística - PPGEs, Câmpus São Carlos, 10/10/2014)
      The main objective of this research is to provide statistical tools that allow the comparison of individuals in a speci ed sports category. Particularly, the present study is focused on the performance evaluation in ...
