A New Zero–Inflated Regression Model with Applications to Australian Health Survey and Biochemistry Graduate Students Data

open access: yesJournal of Mathematics
In this study, we propose a new zero-inflated regression model as an alternative to zero-inflated regression models, such as the zero-inflated Poisson, zero-inflated negative binomial, zero-inflated hurdle-Poisson, and zero-inflated hurdle negative ...

Comparison of the Performance of the Gradient and Newton-Raphson Method to Estimate Parameters in Some Zero-Inflated Regression Models

open access: yesJournal of Advanced Engineering and Computation, 2020
This paper compares the performance of the gradient and Newton-Raphson (N-R) method to estimate parameters in some zero-inflated (ZI) regression models such as the zero-inflated Poisson (ZIP) model, zero-inflated Bell (ZIBell) model, zero-inflated ...

Improved shrinkage estimators in zero-inflated negative binomial regression model

open access: yesHacettepe Journal of Mathematics and Statistics, 2021
‎Zero-inflated negative binomial model is an appropriate choice to model count response variables with excessive zeros and over-dispersion simultaneously. ‎This paper addressed parameter estimation in the zero-inflated negative binomial model when there are many parameters, ‎so that some of them have not influence on the response variable. ‎We proposed

Negative Binomial Two-Parameter Lindley generalized linear model for modeling count data

open access: yesResearch in Statistics
Zero-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

Bayesian model selection reveals biological origins of zero inflation in single-cell transcriptomics

open access: yesGenome Biology, 2020
Background Single-cell RNA sequencing is a powerful tool for characterizing cellular heterogeneity in gene expression. However, high variability and a large number of zero counts present challenges for analysis and interpretation.

Improved Confidence Interval Estimation for Zero-Inflated Count Data Using Transformed Two-Part Bootstrap

open access: yesAppliedMath
This study proposes a transformed two-part bootstrap confidence interval (TTB-CI) for zero-inflated count data. The method combines a standard zero-inflated mixture formulation, parametric bootstrap, and monotone transformations to improve inference for ...
