Objective: Many studies demonstrated that watching violent media content reinforces violent
behavior in young viewers, and stress the need for successful interventions for moderating …

Software fault data with many zeroes in addition to large non‐zero values are common in the
software estimation area. A two‐component prediction approach that provides a robust way …

Unobserved heterogeneity causing overdispersion and the excessive number of zeros take
a prominent place in the methodological development on count modeling. An insight into the …

We analyse lymphoid leukemia incidence data collected between 1988 and 2002 from the
cancer registry of Haut-Rhin, a region in north-east France. For each patient, sex, area of …

In many tornado climate studies, the number of tornado touchdowns is often the primary
outcome of interest. These outcome measures are usually generated under a …

Although there is substantial literature on the univariate zero-truncated Poisson (ZTP)
distributions, few works have been done for developing multivariate ZTP distributions with …

In this research article, we propose a class of models for positive and zero responses by
means of a zero‐augmented mixed regression model. Under this class, we are particularly …

Excessive zeros in multivariate count data are often observed in scenarios of biomedicine
and public health. To provide a better analysis on this type of data, we first develop a …

The zero-inflated Poisson regression (ZIP) in many situations is appropriate for analyzing
multilevel correlated count data with excess zeros. In this paper, a score test for assessing …

Bounded data with excess observations at the boundary are common in many areas of
application. Various individual cases of inflated mixture models have been studied in the …
