Improved likelihood inference for the shape parameter in Weibull regression
(TAYLOR & FRANCIS LTD, 2008)
We obtain adjustments to the profile likelihood function in Weibull regression models with and without censoring. Specifically, we consider two different modified profile likelihoods: (i) the one proposed by Cox and Reid ...
Second-order biases of maximum likelihood estimates in overdispersed generalized linear models
(2001)
In this paper, we derive general formulae for second-order biases of maximum likelihood estimates in overdispersed
generalized linear models, thus generalizing results by Cordeiro and McCullagh (J. Roy. Statist. Soc. Ser. ...
Eliminação de parâmetros perturbadores em um modelo de captura-recaptura
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 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, ...
Eliminação de parâmetros perturbadores na estimação de tamanhos populacionais
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2010-01-15)
In this study, we used the capture-recapture procedure to estimate the size of a closed population. We analysed three di_erent statistics models. For each one of these models we determined - through several methods of ...
A note on the likelihood and moments of the skew-normal distribution
(INST ESTADISTICA CATALUNYA-IDESCAT, 2008)
In this paper an alternative approach to the one in Henze (1986) is proposed for deriving the odd moments of the skew-normal distribution considered in Azzalini (1985). The approach is based on a Pascal type triangle, which ...
On the mathematical foundations of likelihood theory
(Universidade Federal de Minas GeraisUFMG, 2017-12-15)
We discuss a general definition of likelihood function in terms of Radon-Nikodým derivatives.The definition is validated by the Likelihood Principle once we establish a result regarding the proportionality of likelihood ...
The Poisson-exponential lifetime distribution
(2011-01-01)
In this paper we proposed a new two-parameters lifetime distribution with increasing failure rate. The new distribution arises on a latent complementary risk problem base. The properties of the proposed distribution are ...
