Procedimentos sequenciais Bayesianos aplicados ao processo de captura-recaptura
(Universidade Federal de São Carlos, 2014-05-30)
In this work, we make a study of the Bayes sequential decision procedure applied to capture-recapture with fixed sample sizes, to estimate the size of a finite and closed population process. We present the statistical ...
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 ...
Novos modelos de sobrevivência com fração de cura baseados no processo da carcinogênese
(Universidade Federal de São Carlos, 2012-05-03)
In this dissertation we propose new models for survival with cure fraction to describe the biological mechanism of the event of interest (cancer) in studies of carcinogenesis in the presence of competing causes latent ...
Modelos de regressão binomial correlacionada
(Universidade Federal de São Carlos, 2012-05-18)
In this thesis, a class of correlated binomial regression models is proposed. The model is based on the generalized binomial distribution proposed by Luceño (1995) and Luceño & Ceballos (1995). The regression structure is ...
Parametric and semi-parametric cure rate models with spatial frailties for interval-censored data
(Universidade Federal de São Carlos, 2016-05-31)
In this thesis, we extend some flexible cure rate models, such as the geometric, negative
binomial and power series cure rate models, to allow for spatial correlations by including spatial
frailties for the interval ...
Modelagem de dados de sobrevivência com eventos recorrentes via fragilidade discreta
(Universidade Federal de São Carlos, 2015-09-02)
In this thesis it is proposed alternative methodologies and extensions on
models for recurrent event data. Speci cally, we propose a model in which
the distribution of the gap time is easily derived from the marginal ...
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 ...
Um método para construção de distribuições de probabilidades do tipo contínuo
