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 ...
Modelos de regressão logística clássica, Bayesiana e redes neurais para Credit Scoring
(Universidade Federal de São Carlos, 2008-02-15)
Important advances have been achieved in the granting of credit, however, the problem of identifying good customers for the granting of credit does not provide a definitive solution. Several techniques were presented and ...
Uma abordagem clássica e bayesiana para o modelo de Tweedie
(Universidade Federal de São Carlos, 2005-04-27)
The goal of this work is to present a classic and a bayesian approach to the Tweedie Compound Poisson model considering the form and application shown at Jorgensen & Souza (1992). A speci.c goal is to estimate the individual ...
Inferência bayesiana para o tamanho de uma população fechada com erros de registros de dados amostrais
(Universidade Federal de São Carlos, 2008-06-12)
In this dissertation we determine maximum likelihood and bayesian estimates of the size of a closed population, from two lists of data of elements of the population. It has been supposed that the registers of the individual ...
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 ...
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 ...
Inferência bayesiana objetiva e freqüentista para a probabilidade de sucesso
(Universidade Federal de São Carlos, 2009-02-10)
This study considers two discrete distributions based on Bernoulli trials: the Binomial and the Negative Binomial. We explore credibility and confidence intervals to estimate the
probability of success of each distribution. ...
Modelo de mistura com número de componentes desconhecido: estimação via método split-merge
(Universidade Federal de São Carlos, 2009-11-30)
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 de regressão com erros normais assimétricos: uma abordagem bayesiana
(Universidade Federal de São Carlos, 2005-12-13)
The statistical analysis of the continuous data set has been developed in most cases for normal models, specially, in the linear and nom linear models context. In the simple linear regression models, even accepting as ...
