• Modelo de mistura com número de componentes desconhecido: estimação via método split-merge 

      Saraiva, Erlandson Ferreira (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Estatística - PPGEs, , 30/11/2009)
      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 com mistura de multinomiais aplicado à identificação de proteínas similares. 

      Coimbra, Ricardo Galante (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Estatística - PPGEs, , 24/02/2005)
      The proteins are important molecules from the cells, whereas they take part since the construction of cell´s framing until the transmission of the genetic information between the generations. A protein can be characterized ...
    • Modelo de mistura padrão de longa duração com censura uniforme-exponencial 

      Chaves, Josenildo de Souza (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Estatística - PPGEs, , 25/03/2010)
      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 ...
    • Modelo de mistura padrão com tempo de falha exponencial e censura informativa 

      Freitas, Luiz Antonio de (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Estatística - PPGEs, , 25/06/2010)
      In this work we consider the long-term survival model introduced by Berkson & Gage (1952), for modeling survival data of nonhomogeneous populations, where a subpopulation does not present the event of interest, despite a ...
