Associated factor of mortality rate amongst patients with AIDS and HIV-TB co-infections using zero inflated negative binomial method
… as count data with a preponderance of zeros. Data in the form of counts and proportions arise in many fields such as studies in medicine, public health, toxicology, epidemiology, sociology, psychology, engineering, agriculture and soon. When the dependent variable is a nonnegative count …

Count Data Models for Injury Data from the National Health Interview Survey (NHIS)
… using injury count data from 2006-2011 NHIS. The Zero-Inflated Negative Binomial (ZINB) model turns out to be the optimal count data model for our data. The inferences made from the ZINB regression model are compared with those from the logistic regression model. The results indicate that ZINB …

Legislating Morality: Codes of Ethics and Sanctions Related to Teacher Misconduct
… 12 states over a 10-year period. The author used zero-inflated negative binomial regression and determined that the legislated status and nature of codes of ethics for teachers, average annual teacher salary, states’ right to work status, and union coverage had a relationship with sanctions. …

Understanding theft from the person and robbery of personal property victimisation trends in England and Wales, 1994-2010/11
… statistical methods are utilised including binomial logistic, negative binomial and zero-inflated negative binomial regression. There are a number of proposed contributions to knowledge from this research.

Zero-Inflated Models to Identify Transcription Factor Binding Sites in ChIP-seq Experiments
… and other biases. In this study, we propose a negative binomial model (NB), a zero-inflated Poisson model (ZIP) and a zero-inflated negative binomial model (ZINB) for peak-calling. Using real ChIP-seq datasets, we show that ZINB model is the best model for ChIP-seq data. Then we incorporate …

Changes in Healthcare Utilization and Charges Among Supportive Housing Residents Enrolled in a Health Coaching Program
… the program's influence on their healthcare use. Zero-inflated negative binomial model and log-gamma models were used to assess change in count variables and charged amounts respectively. Although participants reported a positive impact of the program on their overall quality of life through …

An ecological adjusted random effect model for violent and property crime in Windhoek (2011-2016)
Count data that are zero inflated are often analysed using Zero-Inflated Negative Binomial Generalized Linear Mixed Model (ZTNB-GLMM) when observations are correlated in ways that require random effects. The present study investigates ecological factors influencing Violent and Property crime in …

Copula-Based Zero-Inflated Count Time Series Models
… finance. In some cases, a specific count, say zero, may occur more often than usual. Additionally, serial dependence might be found among these counts if they are recorded over time. Overlooking the frequent occurrence of zeros and the serial dependence could lead to false inference. In this …

Global Insights into Oral Hygiene & Gingivitis During Orthodontic Treatment with Artificial Intelligence
… in the longitudinal analyses. Longitudinal zero-inflated negative binomial mixed-effects models revealed a critical mechanistic dissociation: gingivitis trajectories progressively diverged between groups (treatment×time IRR=1.02; χ²=573.54, p<0.001), while hygiene trajectories remained …

Causal Representation Learning for Predicting Genetic Perturbation Effects on Single Cells
… inference (SCVI) architecture, employing a zero-inflated negative binomial output distribution, demonstrates challenges in learning perturbational data distributions. In contrast, a standard VAE architecture with a Gaussian output distribution on normalized gene expressions, when paired with …

Parameter Estimation for Normally Distributed Grouped Data and Clustering Single-Cell RNA Sequencing Data via the Expectation-Maximization Algorithm
… takes into account the large proportion of zeros present in the data, which can be either true biological zeros or technological noise. The assumed model for clustering is a mixture of either zero-inflated Poisson or zero-inflated negative binomial distributions, and inference is conducted …

Race, income, and benefits from national parks
National Parks have become an integral part of global life in both developed and developing countries during the last century. Today, there are more than 1,200 national parks and nature preserves around the world. The U.S. federal government spends more than \$3 billion annually to maintain and …

Factors affecting Western Atlantic red knots (Calidris canutus rufa) and their prey during spring migration on Virginia's barrier islands
… winter counts from Tierra del Fuego to inform zero-inflated negative binomial mixed-effects regression models of red knot site selection and flock size in Virginia. We also used generalized linear mixed-effects regression models to determine how climatic and geomorphological factors affected …
