Miscellanea. Local power of three classic criteria in generalised linear models with unknown dispersion
离散参数未知的广义线性模型中三种经典检验的局部功效
In this paper we obtain asymptotic expansions for the nonnull distribution functions of the likelihood ratio, score and Wald test statistics in exponential family generalised linear models under Pitman alternatives assuming unknown dispersion, thus generalising some of the results in Cordeiro, Botter & Ferrari (1994).
