Abstract:

The diagnostics and influence analysis methods of the generalized binomial regression model were sudied. The estimation of the parameters and the Score test of the dispersion parameters about the model are given. And the influence analysis were sudied base on the case-deletion model and under three kinds of local influence. Finally, two numerical examples illustrateed the effectiveness of the method.

Key words: generalized binomial regression; diagnostics; influence analysis; Score test; generalized Cook distance
