Família Weibull de razão de chances na presença de covariáveis
(Universidade Federal de São Carlos, 2009-03-18)
The Weibull distribuition is a common initial choice for modeling data with monotone hazard rates. However, such distribution fails to provide a reasonable parametric _t when the hazard function is unimodal or bathtub-shaped. ...
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. ...
Comparação das distribuições α-estável, normal, t de student e Laplace assimétricas
(Universidade Federal de São Carlos, 2012-01-27)
Abstract The asymmetric distributions has experienced great development in recent times. They are used in modeling financial data, medical, genetics and other applications. Among these distributions, the Skew normal ...

Análise de referência Bayesiana para o modelo Weibull na aplicação de riscos competitivos
(Universidade Federal de São Carlos, 2009-01-30)
There are situations where various risk factors of failure are present, in the same time, in the life of system. For this reason we say that these factors are competing to cause the system failure. However, only one of ...
Dependência entre perdas em risco operacional
(Universidade Federal de São Carlos, 2014-02-12)
In this work, we present and discuss the operational risk in the financial institutions, Basel Accord II, the structure of dependence between cumulative operational losses, a tool for modeling this dependence (theory of ...
Algumas extensões da distribuição Birnbaum-Saunders: uma abordagem bayesiana
(Universidade Federal de São Carlos, 2012-01-09)
The Birnbaum-Saunders Distribution is based on an physical damage that produces the cumulative fatigue materials, This fatigue was identified as an important cause of failure in engineering structures. Recently, this model ...
Redes probabilísticas de K-dependência para problemas de classificação binária
(Universidade Federal de São Carlos, 2012-02-28)
Classification consists in the discovery of rules of prediction to assist with planning and decision-making, being a continuously indispensable tool and a highly discussed subject in literature. As a special case in ...
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, ...
