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 ...
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 ...
Modelos de sobrevivência com base nas distribuições geométrica e exponencial
(Universidade Federal de São Carlos, 2013-02-01)
In this dissertation we propose four models to model lifetime data. The fist family of distribution is called Exponentiated Complementary Exponential Geometric distribution (ECEG) and it is obtained by exponentiation of ...
Estimadores não paramétricos para dados com censura
(Universidade Federal de São Carlos, 2013-04-19)
In this paper we study the reliability of systems with connected components in series and parallel. For systems in series, the device fails when the first component fails. Although in the parallel systems this happens when ...
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 ...
Modelos de regressão binomial correlacionada
(Universidade Federal de São Carlos, 2012-05-18)
In this thesis, a class of correlated binomial regression models is proposed. The model is based on the generalized binomial distribution proposed by Luceño (1995) and Luceño & Ceballos (1995). The regression structure is ...
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, ...
Modelo destrutivo com variável terminal em experimentos quimiopreventivos de tumores em animais
(Universidade Federal de São Carlos, 2012-04-12)
The chemical induction of carcinogens in chemopreventive animal experiments is becoming increasingly frequent in biological research. The purpose of these biological experiments is to evaluate the effect of a particular ...
