Zero to k Inflated Poisson Regression Models with Applications
Journal of Statistical Theory and Applications (JSTA), 2023 In the count data set, the frequency of some points may occur more than expected under the standard data analysis models. Indeed, in many situations, the frequencies of zero and of some other points tend to be higher than those of the Poisson.

Zero-inflated models for the evaluation of colorectal polyps in colon cancer screening studies—a value-based biostatistics practice [PDF]
PeerJBackground Colon cancer screening studies are needed for the early detection of colorectal polyps to reduce the risk of colorectal cancer. Unfortunately, the data generated on colon polyps are typically analyzed in their dichotomized form and sometimes ...

Regression models for count data with excess zeros: A comparison using survey data [PDF]
Tutorials in Quantitative Methods for Psychology, 2023 Presence of excess zeros and the distributions are major concern in modeling count data. Zero inflated and hurdle models are regression techniques which can handle zero inflated count data.

Zero-inflated Modified Borel-Tanner Regression Model for Count Data
Austrian Journal of Statistics, 2022 By starting from the one-parameter Modified Borel-Tanner distribution proposed recently in the statistic literature, we introduce the zero-inflated Modified Borel-Tanner distribution. Additionally, on the basis of the proposed zero-inflated distribution,

Application of Mixture Models for Doubly Inflated Count Data
Analytics, 2023 In health and social science and other fields where count data analysis is important, zero-inflated models have been employed when the frequency of zero count is high (inflated).

Justification for considering zero-inflated models in crash frequency analysis
Transportation Research Interdisciplinary Perspectives, 2020 One common challenge of modeling intersection related crash data is the high proportion of sites with zero crashes. Extensive research has been done on appropriate methods to handle excess zeroes.
