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 ...
Modelo de mistura com dependência Markoviana de primeira ordem
(Universidade Federal de São Carlos, 2014-09-12)
We present the mixture model with first order dependence, MMM(1). This model corresponds to a redefinition of the hidden Markov model (HMM) where a non observable variable is used to control the mixture. The usual mixture ...
Modelos de regressão bivariados Bernoulli : exponencial
(Universidade Federal de São Carlos, 2013-04-05)
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 ...
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, ...
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 ...

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 ...
Modelagem estatística para a determinação de resultados de dados esportivos
(Universidade Federal de São Carlos, 2007-06-27)
The basic result of a soccer game is the final scoreboard, which can be seen as a
bivariate random vector. Theoretically and based on existent literature we can argue that
the number of marked gols by a team in a game ...
