A Comparison of the Robust Zero-Inflated and Hurdle Models with an Application to Maternal Mortality
Mathematical and Computational ApplicationsThis study evaluates the performance of count regression models in the presence of zero inflation, outliers, and overdispersion using both simulated and real-world maternal mortality dataset.

scMODD: A model-driven algorithm for doublet identification in single-cell RNA-sequencing data
Frontiers in Systems Biology, 2023 Single-cell RNA sequencing (scRNA-seq) data often contain doublets, where a doublet manifests as 1 cell barcode that corresponds to combined gene expression of two or more cells. Existence of doublets can lead to spurious biological interpretations. Here,

Structural zeroes and zero-inflated models.
Shanghai archives of psychiatry, 2014 In psychosocial and behavioral studies count outcomes recording the frequencies of the occurrence of some health or behavior outcomes (such as the number of unprotected sexual behaviors during a period of time) often contain a preponderance of zeroes because of the presence of 'structural zeroes' that occur when some subjects are not at risk for the ...

A Zero‐Inflated Regression Model for Grouped Data [PDF]
Oxford Bulletin of Economics and Statistics, 2014 AbstractWe introduce the (panel) zero‐inflated interval regression (ZIIR) model, which is ideally suited when data are in the form of groups, and there is an ‘excess’ of zero observations. We apply our new modelling framework to the analysis of visits to the general practitioner (GP) using individual‐level data from the British Household Panel Survey ...

Temporal aggregation of migration counts can improve accuracy and precision of trends
Avian Conservation and Ecology, 2016 Temporal replicate counts are often aggregated to improve model fit by reducing zero-inflation and count variability, and in the case of migration counts collected hourly throughout a migration, allows one to ignore nonindependence. However, aggregation

Bayesian Inference for Zero-Modified Power Series Regression Models
MathematicsCount data often exhibit discrepancies in the frequencies of zeros, which commonly occur across various application domains. These data may include excess zeros (zero inflation) or, less frequently, a scarcity of zeros (zero deflation).

Quantifying the impact of inter-site heterogeneity on the distribution of ChIP-seq data
Frontiers in Genetics, 2014 Chromatin Immunoprecipitation followed by sequencing (ChIP-seq) is a valuable tool for epigenetic studies. Analysis of the data arising from ChIP-seq experiments often requires implicit or explicit statistical modelling of the read counts.

The Eclipse of the Goal of Zero Inflation [PDF]
History of Political Economy, 1997 William J. Barber's study of Alvin H. Hansen (1887-1975) emphasized the importance of the intellectual transformation that led to the "'Keynes-Hansen intellectual system that appeared to have compelling diagnostic and prescriptive power" (Barber 19X7.
