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 ...
Modelos de regressão bivariados Bernoulli : exponencial
(Universidade Federal de São Carlos, 2013-04-05)
Um novo estimador exponencial por partes da curva de sobrevivência: um estudo comparativo
(Universidade Federal de São Carlos, 2006-05-31)
In this work we revise the main basic concepts on survival analysis and reliability.
We present the most known nonparametric estimators of the survival function in the
presence of censured data. Their estimates are ...
Uma proposta para análise de dados com correlação espacial e temporal
(Universidade Federal de São Carlos, 2007-09-27)
In several research areas, the study of the occurrence of a phenomenon over a
period of time is very common. In this case, if we use the theory of Generalized Linear
Models to analyze the subject of interest, we ll have, ...

Ponderação de modelos com aplicação em regressão logística binária
(Universidade Federal de São Carlos, 2006-04-18)
This work consider the problem of how to incorporate model selection uncertainty
into statistical inference, through model averaging, applied to logistic regression. It will
be used the approach of Buckland et. al. (1997), ...
Modelos para dados de contagem: um estudo sobre o número de ovos do mosquito Aedes aegypti
(Universidade Federal de São Carlos, 2007-07-22)
In this work we considered four types of models for count data: the
Poisson model, the Negative Binomial Model and variations of these
models for count inflated of zeros (ZIP and ZINB).
Information on the number of put ...
Uso de métodos bayesianos em testes de vida acelerados no controle da qualidade de produtos industriais
(Universidade Federal de São Carlos, 2006-03-03)
In this work, we introduce a Bayesian approach for quality control of industrial products, assuming units in test under stress levels higher than the usual level. We assume di¤erent distributions for the lifetimes of the ...
Modelos de resposta ao item com função de ligação t-assimétrica
(Universidade Federal de São Carlos, 2007-04-20)
The Item Response Theory (IRT) is a set of mathematical models representing the probability of an individual to take a correct response of an item and its ability. The purpose of our research is to show the models formulated ...
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 ...
