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. ...
Classe de distribuições série de potências inflacionadas com aplicações
(Universidade Federal de São Carlos, 2009-04-06)
This work has as central theme the Inflated Modified Power Series Distributions, where the objective is to study its main properties and the applicability in the bayesian context. This class of models includes the generalized ...
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 ...
Reamostragem bootstrap em amostragem por conjuntos ordenados e intervalos de confiança não paramétricos para a média.
(Universidade Federal de São Carlos, 2005-01-27)
Ranked set sampling is an efficient and practice way to obtain more precise estimative
when the sample size is small because of the high cost or difficulties to measure the interest
variable. Using rough and cheap qualitative ...
Uma modificação da extensão do algoritmo AID para modelos lineares generalizados usando reamostragem Bootstrap
(Universidade Federal de São Carlos, 2006-03-03)
One of the most frequently situation found by researchers is to find groups of similar individuals. The cluster analysis is a set of statistical techniques that identify mutually exclusive subgroups or classes over ...
Intervalos de confiança para dados com presença de eventos recorrentes e censuras.
(Universidade Federal de São Carlos, 2003-05-23)
In survival analysis and reliability is common that the population units in study presents
recurrence events and censoring ages, besides, is possible to exist a cost related to each event
that happens. The objectives of ...
Aplicações em meta-análise sob um enfoque bayesiano usando dados médicos.
(Universidade Federal de São Carlos, 2006-03-21)
In this work, we consider the use of Meta-analysis with a Bayesian approach. Meta-analysis is a statistical technique that combines the results of di¤erent independent studies with purpose to find general conclusions. This ...
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 ...
Uma abordagem clássica e bayesiana para os modelos de Gompertz e de Richards heteroscedásticos.
(Universidade Federal de São Carlos, 2005-09-16)
This work presents a classical and a Bayesian approaches to two sigmoidal grownth curves, the Gompertz and the Richards models. We consider the homoscedastic assumption and a multiplicative heteroscedastic structure. For ...
