| Abstract: | In this paper, the equivalence of case deletion model（CDM） and mean shift outlier model（MSOM） in longitudinal mixed effect linear models have been studied, the M-estimation of β is get based on Fisher scoring method .The diagnostic statistics based on the above two models are investigated by the grape sugar data example. |
