Background and aims We analyze the possible predictive variables for Adverse Events
(AEs) during sedation for gastrointestinal (GI) endoscopy. Methods We consider 23,788 GI …

The zero-inflated binomial (ZIB) regression model was proposed to account for excess zeros
in binomial regression. Since then, the model has been applied in various fields, such as …

A general class of mixed Poisson regression models is introduced. This class is based on a
mixing between the Poisson distribution and a distribution belonging to the exponential …

The one‐inflated positive Poisson mixture model (OIPPMM) is presented, for use as the
truncated count model in Horvitz–Thompson estimation of an unknown population size. The …

Background: Drug use is a chronic and recurrent disease, and many individuals return to
using drugs a short time after rehabilitation treatment. This study investigated factors …

We investigate inverse-probability-weighted (IPW) maximum likelihood estimation in zero-
inflated binomial regression with missing-at-random covariates. Large sample properties …

Hemoparasites can affect wild birds in numerous ways, but the role of infection occurrence
and intensity on bird physiology and morphology is still little known. Secondary sexual …

This study proposes an efficacious approach to analyze the over-dispersed insurance
frequency data as it is imperative for the insurers to have decisive informative insights for …

In this paper, we are interested in the robustness of the estimation in the Zero-Inflated
Poisson regression model, when varying the class membership model of the underlying …

When overdispersion and zero-inflated feature are both concerned, Zero-inflated negative
binomial (ZINB) model tends to be more appropriate than the popular Zero-inflated Poisson …
