In the presence of zero-inflation, the ZINB or HUNB model is recommended to account for additional heterogeneity. In addition to model fit and interpretability, choosing between a zero-inflated or ...

We analyze a subset of the IFS data by a marginal regression model with a zero-inflated version of the Conway–Maxwell–Poisson distribution for count data exhibiting excessive zeros and a wide range of ...

Models with a significantly higher number of zeros are known as zero-inflated models. Poisson regression models provide a standard framework for the analysis of count data. However, count data is ...

Motivated by the idea of Liu and Tian (Computational Statistics and Data Analysis, 83, 200-222; 2015), we develop a multivariate zero-inflated hurdle model to describe multivariate count data with ...
