Poisson回归模型的局部影响分析

Local Influence Analysis for Poisson Regression Model

本文讨论了Poisson回归模型的局部影响分析,分别针对方差加权扰动模型、响应变量扰动模型、自变量扰动模型得到了相应的影响矩阵和影响曲率的计算公式,并通过实际例子验证了本文诊断方法的有效性。

This paper studies the local mulas of influence curvature and influence influence for Poisson regression model. The counting formatrix for case -weights perturbation model, mean shift perturbation model and arguments perturbation model are obtained. Finally the numerical example illustrates that the method is effective.
