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 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 ...
Uso do processo gama para dados de sobrevivência.
(Universidade Federal de São Carlos, 2005-01-20)
In this dissertation, we introduce classical and Bayesian approaches to get inferences
on the parameters of interest, considering exponential and Weibull distributions for the
lifetimes. For a Bayesian analysis, we assume ...
Modelagem de dados de sobrevivência via modelo de risco logístico generalizado
(Universidade Federal de São Carlos, 2005-03-30)
The modeling of data of survival with the presence of covariáveis by means of the risk function
has been each used time more had the easiness of interpretation One of the examples most important
of risk models is the model ...
Modelo com mistura de multinomiais aplicado à identificação de proteínas similares.
(Universidade Federal de São Carlos, 2005-02-24)
The proteins are important molecules from the cells, whereas they take part since the construction of cell´s framing until the transmission of the genetic information between the generations. A protein can be characterized ...
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 ...
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 ...
Metodologia gráfica para dados de eventos recorrentes via bootstrap.
(Universidade Federal de São Carlos, 2005-01-05)
Experiments related to recurrent events provide information about the number of events,
time to their ocurrence and their costs. Nelson (1995) presents a methodology to obtain
confidence intervals for the cost and the ...
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 ...
