Goodness-of-fit test in parametric mixed effects models based on estimation of the error distribution
基于误差分布估计的参数混合效应模型拟合优度检验
We address the problem of testing for a parametric function of fixed effects in mixed models. We propose a test based on the distance between two empirical error distribution functions, which are constructed from residuals calculated under the opposing hypotheses. The proposed test statistic has power against all alternatives, and its asymptotic distribution is derived. A simulation study shows that the test outperforms others in the literature. The test is applied to…
