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, ...
Análise bayesiana objetiva para as distribuições normal generalizada e lognormal generalizada
(Universidade Federal de São Carlos, 2014-11-21)
The Generalized Normal (GN) and Generalized lognormal (logGN) distributions are flexible for accommodating features present in the data that are not captured by traditional distribution, such as the normal and the lognormal ...
Modelos de sobrevivência com fração de cura via partição bayesiana
(Universidade Federal de São Carlos, 2014-05-30)
In general, models for survival data with a cure fraction relate the cure fraction with the covariates using different link functions, for example, the logit link function and do not consider the problem of selection of ...
Modelos de sobrevivência bivariados baseados na cópula FGM : uma abordagem bayesiana
(Universidade Federal de São Carlos, 2012-02-07)
In this work we present a Bayesian analysis for bivariate survival data in the presence of a covariate and censored observations. We propose a bivariate distribution for the bivariate survival times based on the ...
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 ...
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 ...
