Modelos para dados de sobrevivência na presença de diferentes esquemas de ativação baseados na distribuição geométrica
(Universidade Federal de São Carlos, 2013-04-08)
In this thesis new families of survival distributions are proposed. Those distributions are derived by assuming a latent activation structure to explain the occurrence of the event of interest. In general, the competitive ...
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 ...

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 ...
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 ...
