O método de máxima Lq-verossimilhança em modelos com erros de medição
(Universidade Federal de São Carlos, 2012-02-29)
In this work we consider a new estimator proposed by Ferrari & Yang (2010), called the maximum Lq-likelihood estimator (MLqE), to estimate the parameters of the measurement error models, in particular, the structural model. ...
Uma nova abordagem para análise de dependência bivariada
(Universidade Federal de São Carlos, 2010-04-23)
In this dissertation we describe and implement procedures for nonparametric estimation of copulas and Sibuya function, and also procedures for bivariate analysis of dependence based on the behavior of their contours plot. ...
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 ...
Modelo de mistura padrão com tempos de vida exponenciais ponderados
(Universidade Federal de São Carlos, 2010-03-05)
In this work, we brie_y introduce the concepts of long-term survival analysis. We dedicated ourselves exclusively to the standard mixture cure model from Boag (1949) and Berkson & Gage (1952), showing its deduction and ...
Utilização de técnicas bayesianas em modelos de regressão de Poisson para dados de contagem longitudinais e dados de contagem com medidas repetidas apresentando excesso de zeros
(Universidade Federal de São Carlos, 2008-06-09)
In medical and biological researches we often .nd count data. For longitudinal count data, usual Poisson regression models, assuming independence among observations, are not applicable because of the correlation of these ...
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 ...
Métodos de agrupamento na análise de dados de expressão gênica
(Universidade Federal de São Carlos, 2009-02-16)
The clustering techniques have frequently been used in literature to the analyse data in several fields of application. The main objective of this work is to study such techniques. There is a large number of clustering ...
Função de intensidade Poisson perturbada pelo número de ocorrências para dados de eventos recorrentes
(Universidade Federal de São Carlos, 2007-06-22)
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 ...
Abordagem clássica e bayesiana para os modelos de séries temporais da família GARMA com aplicações para dados contínuos
(Universidade Federal de São Carlos, 2011-03-24)
In this work, the aim was to analyze in the classic and bayesian context, the GARMA model with three different continuous distributions: Gaussian, Inverse Gaussian and Gamma. We analyzed the performance and the goodness ...
