A unified Bayesian approach for modeling zero-inflated count and continuous outcomes

This article reexamines zero-inflated count and semi-continuous models for analyzing data exhibiting an excess of zeros. Most of these models seem to share a common structure belonging to the exponential dispersion family (EDF) of distributions and the two-part hurdle model. When examining cross-sectional outcomes with a distribution belonging to the EDF, several hurdle models have been explored. This includes recently utilized models as well …
