Modelos de sobrevivência com fração de cura usando um termo de fragilidade e tempo de vida Weibull modificada generalizada
(Universidade Federal de São Carlos, 2011-02-24)
In survival analysis, some studies are characterized by having a significant fraction of units that will never suffer the event of interest, even if accompanied by a long period of time. For the analysis of long-term data, ...
O método de máxima Lq-verossimilhança em modelos com erros de medição
(Universidade Federal de São Carlos, 2012-02-29)
In this work we consider a new estimator proposed by Ferrari & Yang (2010), called the maximum Lq-likelihood estimator (MLqE), to estimate the parameters of the measurement error models, in particular, the structural model. ...
Modelagem de eventos raros: um estudo comparativo
(Universidade Federal de São Carlos, 2012-01-16)
In some situations, in various areas of knowledge, the response variable of interest has dichotomous distribution extremely unbalanced. In the _nancial market is the common interest in determining the probability that each ...
Uma nova abordagem para análise de dependência bivariada
(Universidade Federal de São Carlos, 2010-04-23)
In this dissertation we describe and implement procedures for nonparametric estimation of copulas and Sibuya function, and also procedures for bivariate analysis of dependence based on the behavior of their contours plot. ...
Modelos de regressão PLS com erros heteroscedásticos
(Universidade Federal de São Carlos, 2010-01-26)
Two problems related to Partial Least Squares method are considered in this work. Heteroscedastic errors and an asymmetrical error distribution. In the _rst part of this work a methodology is developed which allows, based ...
Avaliação de testes diagnósticos na ausência de padrão ouro considerando relaxamento da suposição de independência condicional, covariáveis e estratificação da população: uma abordagem bayesiana
(Universidade Federal de São Carlos, 2011-12-16)
The application of a gold standard reference test in all or part of the sample under investigation is often not feasible for the majority of diseases affecting humans, either by a lack of consensus on which testing may be ...
Eliminação de parâmetros perturbadores na estimação de tamanhos populacionais
(Universidade Federal de São Carlos, 2010-01-15)
In this study, we used the capture-recapture procedure to estimate the size of a closed population. We analysed three di_erent statistics models. For each one of these models we determined - through several methods of ...
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 ...
Modelo logístico generalizado dependente do tempo com fragilidade
(Universidade Federal de São Carlos, 2011-02-11)
Several authors have preferred to model survival data in the presence of covariates through the hazard function, a fact related to its interpretation. The hazard function describes as the instantaneous average of failure ...
