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…
