Modelos alternativos em filas M/G/1
(Universidade Federal de São Carlos, 2015-11-26)
The main aim of this work is to develop alternative queuing models to M/ G/l, in which arrivals follow a Poisson process, the total number of customers on the system and the total number of service channels are unknown. ...
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 ...
Modelos série de potência com excesso de zeros observáveis e latentes
(Universidade Federal de São Carlos, 2016-09-28)
The present work's main objective is to study the significance of zeros in an observable
and latent data. In observable data set that occur excess of zeros, its common to have
sobredispersion. In this sense, the models ...
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, ...
Análise estatística do modelo de Nelson e Siegel
(Universidade Federal de São Carlos, 2013-03-21)
The present paper studies the yield curve, an important tool for financial decisions, due to its fundamental role in the implementation and evaluation of monetary policies by the central banks. It also shows market ...
Modelos de sobrevivência com fração de cura via partição bayesiana
(Universidade Federal de São Carlos, 2014-05-30)
In general, models for survival data with a cure fraction relate the cure fraction with the covariates using different link functions, for example, the logit link function and do not consider the problem of selection of ...
Novos modelos de sobrevivência com fração de cura baseados no processo da carcinogênese
(Universidade Federal de São Carlos, 2012-05-03)
In this dissertation we propose new models for survival with cure fraction to describe the biological mechanism of the event of interest (cancer) in studies of carcinogenesis in the presence of competing causes latent ...
Modelos dinâmicos de resposta binária para dados em painel
(Universidade Federal de São Carlos, 2008-06-06)
A summary of the state of the art relative to regression models for binary response variable and panel data is presented in this work. Those models may include efects from several sources: specific variables of interest, ...
Modelagem de fraude em cartão de crédito
(Universidade Federal de São Carlos, 2008-09-02)
The transactions volume increase brought the fraud increase, which result in a annual loss of billions of reais to all .nancial institutions in the world. Therefore, it.s very important the development of detection methods ...
