Comparação das distribuições α-estável, normal, t de student e Laplace assimétricas
(Universidade Federal de São Carlos, 2012-01-27)
Abstract The asymmetric distributions has experienced great development in recent times. They are used in modeling financial data, medical, genetics and other applications. Among these distributions, the Skew normal ...

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 ...
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 ...
Família Weibull de razão de chances na presença de covariáveis
(Universidade Federal de São Carlos, 2009-03-18)
The Weibull distribuition is a common initial choice for modeling data with monotone hazard rates. However, such distribution fails to provide a reasonable parametric _t when the hazard function is unimodal or bathtub-shaped. ...
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 ...
Modelagem de eventos raros: um estudo comparativo
(Universidade Federal de São Carlos, 2012-01-16)
In some situations, in various areas of knowledge, the response variable of interest has dichotomous distribution extremely unbalanced. In the _nancial market is the common interest in determining the probability that each ...
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 ...
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 ...
