Análise bayesiana objetiva para as distribuições normal generalizada e lognormal generalizada
(Universidade Federal de São Carlos, 2014-11-21)
The Generalized Normal (GN) and Generalized lognormal (logGN) distributions are flexible for accommodating features present in the data that are not captured by traditional distribution, such as the normal and the lognormal ...
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 ...
Procedimentos sequenciais Bayesianos aplicados ao processo de captura-recaptura
(Universidade Federal de São Carlos, 2014-05-30)
In this work, we make a study of the Bayes sequential decision procedure applied to capture-recapture with fixed sample sizes, to estimate the size of a finite and closed population process. We present the statistical ...
Modelos mistos semiparamétricos parcialmente não lineares
(Universidade Federal de São Carlos, 2014-03-28)
Correlated data sets with nonlinear structure are common in many areas such as biostatistics, pharmacokinetics and longitudinal studies. Nonlinear mixed-effects models are useful tools to analyse those type of problems. ...
Modelagem estatística para análise de dados imobiliários completos e com censura à esquerda
(Universidade Federal de São Carlos, 2014-04-01)
The real estate market has a key role in the country and counties economy attracting several studies and researches that explains and interpret the numerous transactions performed, and especially to find appropriate ways ...
Inferência em modelos de regressão com erros de medição sob enfoque estrutural para observações replicadas
(Universidade Federal de São Carlos, 2014-03-10)
The usual regression model fits data under the assumption that the explanatory variable is measured without error. However, in many situations the explanatory variable is observed with measurement errors. In these cases, ...
Estimação do tamanho populacional a partir de um modelo de captura-recaptura com heterogeneidade
(Universidade Federal de São Carlos, 2014-03-14)
In this work, we consider the estimation of the number of errors in a software from a closed population. The process of estimating the population size is based on the capture-recapture method which consists of examining ...
Capacidade preditiva de Modelos Credit Scoring em inferência dos rejeitados
(Universidade Federal de São Carlos, 2014-03-28)
Granting credit to an applicant is a decision made in a context of uncertainty. At the moment the lender decides to grant a loan or credit sale there is always the possibility of loss, and, if it is associated with a ...
Risco operacional: o cálculo do capital regulatório usando dependência
(Universidade Federal de São Carlos, 2014-01-16)
In this paper we propose a new method for the calculation of regulatory capital required for operational risk. This method is based on some important assumptions for calculation of this capital, for instance, expert opinion, ...
Algoritmo ejeção-absorção metropolizado para segmentação de imagens
(Universidade Federal de São Carlos, 2014-12-19)
We proposed a new split-merge MCMC algorithm for image segmentation. We describe how an image can be subdivided into multiple disjoint regions, with each region having an associated latent indicator variable. The latent ...
