# 半参数非线性再生散度混合效应模型的参数估计和影响分析 Asymptotic Properties of Estimation and Influence Diagnostics on Semiparametric Nonlinear Reproductive Dispersion Mixed-Effects Models

Abstract: This paper proposes several case-deletion and local influence measures for assessing the influence of an observation for semiparametric nonlinear reproductive dispersion mixed-effects models. The essential idea is to treat the latent random effects in the model as missing data and estimate unknown parameters by MCNR algorithm. On the basis of the Q-function which is associated with the conditional expectation of the complete-data log-likelihood, we generate generalized Cook Distance. Three different perturbation schemes are discussed. Finally, the proposed methods are illustrated by the simulation analysis and one real data set.
