The zero inflated negative binomial – Crack distribution: some properties and parameter estimation [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2015 The zero inflated negative binomial-Crack (ZINB-CR) distribution is a mixture of Bernoulli distribution and negative binomial-Crack (NB-CR) distribution, which is an alternative distribution for the excessive zero counts and overdispersion.

Zero-inflation in the Multivariate Poisson Lognormal Family
Statistics and ComputingAbstract Analyzing high-dimensional count data is a challenge and statistical model-based approaches provide an adequate and efficient framework thatpreserves explainability. The (multivariate) Poisson-Log-Normal (PLN) modelis one such model: it assumes count data are driven by an underlying structuredlatent Gaussian variable, so that the ...

Negative Binomial Two-Parameter Lindley generalized linear model for modeling count data
Research in StatisticsZero-inflated data, characterized by excessive zero counts, is a common challenge in various fields, particularly in insurance data. In most cases, count data exhibits overdispersion and excess zeros; models that fail to account for these characteristics

Finding the Right Distribution for Highly Skewed Zero-inflated Clinical Data
Epidemiology, Biostatistics and Public Health, 2022 Discrete, highly skewed distributions with excess numbers of zeros often result in biased estimates and misleading inferences if the zeros are not properly addressed.

Multi-parameter joint regression model for longitudinal zero-inflated count data
四川大学学报. 自然科学版Longitudinal zero-inflated count data are gathered from a series of measurements of experimental individuals at multiple time points and possess the very characteristics of longitudinal data， count data and zero-inflated data simultaneously.The number of

Inference for the Parameters of a Zero-Inflated Poisson Predictive Model
RisksIn the insurance sector, Zero-Inflated models are commonly used due to the unique nature of insurance data, which often contain both genuine zeros (meaning no claims made) and potential claims.

Analysis of dental caries using generalized linear and count regression models [PDF]
Revista Română de Statistică, 2013 Generalized linear models (GLM) are generalization of linear regression models, which allow fitting regression models to response data in all the sciences especially medical and dental sciences that follow a general exponential family. These are flexible
