Um método para construção de distribuições de probabilidades do tipo contínuo
(Universidade Federal de São Carlos, 2013-05-10)
Modelo alfa normal assimétrico multivariado para redes de classificação
(Universidade Federal de São Carlos, 2016-03-16)
In this Thesis we expose the proposition of a new class of probability distributions, the so called alpha skew normal multivariate, an extension of the univariate Normal Alpha distribution, introduced by Elal-Olivero (2010). ...
Modelo Weibull modificado de longa duração
(Universidade Federal de São Carlos, 2011-12-07)
When a group of patients is monitored until a pre-established date for observation of the
recurrence time of an event, it is possible that, at the end of the monitoring period, a parcel of such
group has not yet suffered ...
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 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 ...
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, ...
