O método de máxima Lq-verossimilhança em modelos com erros de medição
(Universidade Federal de São Carlos, 2012-02-29)
In this work we consider a new estimator proposed by Ferrari & Yang (2010), called the maximum Lq-likelihood estimator (MLqE), to estimate the parameters of the measurement error models, in particular, the structural model. ...
Comparação das distribuições α-estável, normal, t de student e Laplace assimétricas
(Universidade Federal de São Carlos, 2012-01-27)
Abstract The asymmetric distributions has experienced great development in recent times. They are used in modeling financial data, medical, genetics and other applications. Among these distributions, the Skew normal ...
Estimação clássica e bayesiana para relação espécieárea com distribuições truncadas no zero
(Universidade Federal de São Carlos, 2012-03-23)
In ecology, understanding the species-area relationship (SARs) are extremely important to determine species diversity. SARs are fundamental to assess the impact due to the destruction of natural habitats, creation of ...
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 ...
Uma avaliação de métodos de previsão aplicados à grandes quantidades de séries temporais univariadas
(Universidade Federal de São Carlos, 2012-12-06)
Time series forecasting is probably one of the most primordial interests on economics and econometrics, and the literature on this subject is extremely vast. Due to technological growth in recent decades, large amounts of ...
Combinação de classificadores para inferência dos rejeitados
(Universidade Federal de São Carlos, 2012-03-16)
In credit scoring problems, the interest is to associate to an element who request some kind of credit, a probability of default. However, traditional models uses samples biased because the data obtained from the tenderers ...
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 ...
