Uma abordagem bayesiana para análise de fraude de subscrição em telecomunicações
(Universidade Federal de São Carlos, 2006-06-09)
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 ...
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 ...
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 ...
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 ...
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 ...
Modelo de mistura padrão com tempo de falha exponencial e censura informativa
(Universidade Federal de São Carlos, 2010-06-25)
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 ...
Modelo bayesiano de coincidências em processos de listagens
(Universidade Federal de São Carlos, 2006-05-03)
In this work we present a bayesian methodology to estimate the number of coincident
individuals of two lists, considering the occurrence of correct and incorrect registers of the
informations registers of each individual ...
