In this paper we deal with the class of zero-inflated over-dispersed generalized linear models and propose procedures based on score tests for selecting a model that fits such data.

Generalized linear mixed model We use a binomial trait as an example to demonstrate the new methodology, although the method can be applied to other discrete traits.
