Modelo de mistura padrão com tempo de falha exponencial e censura informativa
(Universidade Federal de São Carlos, 2010-06-25)
In this work we consider the long-term survival model introduced by Berkson & Gage (1952), for modeling survival data of nonhomogeneous populations, where a subpopulation does not present the event of interest, despite a ...
Inferência bayesiana para o tamanho de uma população fechada com erros de registros de dados amostrais
(Universidade Federal de São Carlos, 2008-06-12)
In this dissertation we determine maximum likelihood and bayesian estimates of the size of a closed population, from two lists of data of elements of the population. It has been supposed that the registers of the individual ...
Modelos para dados de sobrevivência na presença de diferentes esquemas de ativação baseados na distribuição geométrica
(Universidade Federal de São Carlos, 2013-04-08)
In this thesis new families of survival distributions are proposed. Those distributions are derived by assuming a latent activation structure to explain the occurrence of the event of interest. In general, the competitive ...
Uma classe de modelos de regressão bivariados para respostas discreta e contínua
(Universidade Federal de São Carlos, 2016-01-28)
In this thesis, a wide general class of models for mixed responses is proposed in which joint distributions are constructed by the conditional approach (probability density functions, (pdf), as the product of a marginal ...
Time series forecasting : advances on Theta method
(Universidade Federal de São Carlos, 2016-05-13)
Accurate and robust forecasting methods for univariate time series are critical as the historical data can be used in the strategic planning of such future operations as buying and selling to ensure product inventory and ...
Defective models for cure rate modeling
(Universidade Federal de São Carlos, 2016-04-01)
Modeling of a cure fraction, also known as long-term survivors, is a part of survival analysis. It studies cases where supposedly there are observations not susceptible to the event of interest. Such cases require special ...
Um método para construção de distribuições de probabilidades do tipo contínuo
(Universidade Federal de São Carlos, 2013-05-10)
Modelos não lineares truncados mistos para locação e escala
(Universidade Federal de São Carlos, 2015-01-14)
We present a class of nonlinear truncated mixed-effects models where the truncation nature of the data is incorporated into the statistical model by assuming that the variable of interest, namely the truncated variable, ...
Eliminação de parâmetros perturbadores em um modelo de captura-recaptura
(Universidade Federal de São Carlos, 2011-11-18)
The capture-recapture process, largely used in the estimation of the number of elements of animal population, is also applied to other branches of knowledge like Epidemiology, Linguistics, Software reliability, Ecology, ...
Algoritmo ejeção-absorção metropolizado para segmentação de imagens
(Universidade Federal de São Carlos, 2014-12-19)
We proposed a new split-merge MCMC algorithm for image segmentation. We describe how an image can be subdivided into multiple disjoint regions, with each region having an associated latent indicator variable. The latent ...
