Abstract:	Two-component Hierarchical Bayesian methods are proposed to model count data with too many zeros when some intervention (treatment) changes the rare event generating process. The models are also expanded to take into account the heterogeneity and correlations existing in the data. Details of the model fitting, checking and selecting alternative models will be presented. The proposed methods are applied to count data on the assessment of an efficacy of pesticides in controlling the reproduction of whiteflies.
