A Score-type Test for Heterogeneity in Zero-inflated Models in a Stratified Population
We propose a score-type statistic to evaluate heterogeneity in zero-inflated models for count data in a stratified population, where heterogeneity is defined as instances in which the zero counts are generated from two sources. Evaluating heterogeneity in this class of models has attracted considera...
