Exponentiated Weibull-logarithmic Distribution: Model, Properties and Applications
Eisa Mahmoudi, Afsaneh Sepahdar, Artur Lemonte
In this paper, we introduce a new four-parameter generalization of the exponentiated Weibull (EW) distribution, called the exponentiated Weibull-logarithmic (EWL) distribution, whi…
Improved likelihood inference in generalized linear models
Tiago M. Vargas, Silvia L. P. Ferrari, Artur J. Lemonte
We address the issue of performing testing inference in generalized linear models when the sample size is small. This class of models provides a straightforward way of modeling nor…
Gradient statistic: higher-order asymptotics and Bartlett-type correction
Tiago M. Vargas, Silvia L. P. Ferrari, Artur J. Lemonte
We obtain an asymptotic expansion for the null distribution function of thegradient statistic for testing composite null hypotheses in the presence of nuisance parameters. The expa…
Skewed Multivariate Birnbaum-Saunders Distributions
Artur J. Lemonte, Guillermo Martínez-Florez, Germán Moreno-Arenas
The univariate Birnbaum-Saunders distribution has been used quite effectively to model times to failure for materials subject to fatigue and for modeling lifetime data. In this art…
Local power of the LR, Wald, score and gradient tests in dispersion models
Artur J. Lemonte, Silvia L. P. Ferrari
We derive asymptotic expansions up to order for the nonnull distribution functions of the likelihood ratio, Wald, score and gradient test statistics in the class of disp…
Testing hypotheses in the Birnbaum-Saunders distribution under type-II censored samples
Artur J. Lemonte, Silvia L. P. Ferrari
The two-parameter Birnbaum-Saunders distribution has been used succesfully to model fatigue failure times. Although censoring is typical in reliability and survival studies, little…
