O processo de Poisson estendido e aplicações
(Universidade Federal de São Carlos, 2007-06-14)
Abstract
In this dissertation we will study how extended Poisson process can be applied to
construct discrete probabilistic models. An Extended Poisson Process is a continuous
time stochastic process with the state space ...
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. ...
Métodos estatísticos aplicados à análise da expressão gênica
(Universidade Federal de São Carlos, 2006-02-23)
The technology of the DNA-Arrays is a tool used to identify and to compare levels of expression of a great number of genes or fragments of genes, in di¤erent conditions.
With this comparison, it is possible to identify ...
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 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 ...
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 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 ...
