| Abstract: | This paper mainly focuses on the diagnostic methods for Logistic regression model.We Systematically studied the impact of the modle analysis,the mean shift modle,Score statistic of outlier.At the same time,derived from the impact of the strong point of identification or diagnosis of abnormal point statistics such as the generalized Cook distance,likelihood distance.And then discussed the local impact analysis,and conducted a case study. |

| Keywords: | Logistic regression model case-deletion means-shift score test local impact analysis |
