RESUMO

In this work, we treated of refinement of tests of hypotheses in symmetric nonlinear regression heteroskedastic models with link function any for the location and for the scale parameter. We developed, in matrix form, a Bartlettâs corrections factor to the likelihood ratio statistic in this class of models. We present, in matrix form, closed-form expressions for Bartlett factors for likelihood location
