Uma família de modelos de regressão com a distribuição original da variável resposta
(Universidade Federal de São Carlos, 2013-04-05)
We know that statistic modeling by regression had a stronger impulse since generalized linear models (GLMs) development in 70 decade beginning of the XX century, proposed by Nelder e Wedderburn (1972). GLMs theory can be ...
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 ...
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 ...
Modelo de regressão com erros normais assimétricos: uma abordagem bayesiana
(Universidade Federal de São Carlos, 2005-12-13)
The statistical analysis of the continuous data set has been developed in most cases for normal models, specially, in the linear and nom linear models context. In the simple linear regression models, even accepting as ...
O efeito de reparametrização em testes de sobrevivência acelerados
(Universidade Federal de São Carlos, 2003-06-11)
Accelerated life tests are frequently used in industrial experiments to obtain measures on the reliability of products. In these tests, the units are submited at higher levels of stress than usual and the informations ...
Especificação do tamanho da defasagem de um modelo dinâmico
(Universidade Federal de São Carlos, 2009-03-06)
Several techniques are proposed to determine the lag length of a dynamic regression model. However, none of them is completely satisfactory and a wrong choice could imply serious problems in the estimation of the parameters. ...
Metodologia gráfica para dados de eventos recorrentes via bootstrap.
(Universidade Federal de São Carlos, 2005-01-05)
Experiments related to recurrent events provide information about the number of events,
time to their ocurrence and their costs. Nelson (1995) presents a methodology to obtain
confidence intervals for the cost and the ...
Inferência do valor de mercado de lotes urbanos. Estudo de caso : município de São Carlos (SP)
(Universidade Federal de São Carlos, 2008-11-13)
In this dissertation we present a regression modelling proposal for modelling the market prices of urban batches at São Carlos city (SP), over the year of 2005. Usual regression modelling and survival techniques, with left ...
Extensões dos modelos de sobrevivência referente a distribuição Weibull
(Universidade Federal de São Carlos, 2014-03-07)
In this dissertation, two models of probability distributions for the lifetimes until the occurrence of the event produced by a specific cause for elements in a population are reviewed. The first revised model is called ...
Distribuição de Poisson bivariada aplicada à previsão de resultados esportivos
(Universidade Federal de São Carlos, 2014-04-23)
The modelling of paired counts data is a topic that has been frequently discussed in several threads of research. In particular, we can cite bivariate counts, such as the analysis of sports scores. As a result, in this ...
