Uma família de modelos de regressão com a distribuição original da variável resposta
(Universidade Federal de São Carlos, 2013-04-05)
We know that statistic modeling by regression had a stronger impulse since generalized linear models (GLMs) development in 70 decade beginning of the XX century, proposed by Nelder e Wedderburn (1972). GLMs theory can be ...
Modeling based on a reparameterized Birnbaum-Saunders distribution for analysis of survival data
(Universidade Federal de São Carlos, 2017-01-09)
In this thesis we propose models based on a reparameterized Birnbaum-Saunder (BS) distribution
introduced by Santos-Neto et al. (2012) and Santos-Neto et al. (2014), to analyze survival data.
Initially we introduce the ...
Modelos alternativos em filas M/G/1
(Universidade Federal de São Carlos, 2015-11-26)
The main aim of this work is to develop alternative queuing models to M/ G/l, in which arrivals follow a Poisson process, the total number of customers on the system and the total number of service channels are unknown. ...
Modelos série de potência com excesso de zeros observáveis e latentes
(Universidade Federal de São Carlos, 2016-09-28)
The present work's main objective is to study the significance of zeros in an observable
and latent data. In observable data set that occur excess of zeros, its common to have
sobredispersion. In this sense, the models ...
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, ...
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 ...
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 ...
