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 ...
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 ...
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 ...
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. ...
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 ...
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 ...
