Defending Zero Inflation: All for Naught [PDF]

Quarterly Review, 1991
Economists and policymakers disagree on the lengths central banks should go in pursuit of price stability and, in fact, on exactly what price stability means. This essay advocates that central banks try to maintain stable price levels in their countries, and it argues that the benefits of achieving this objective are worth the transition costs.

Response to a Defense of Zero Inflation

Quarterly Review, 1991
This essay distills the differences between zero inflation proponents and critics to three main questions: Can the central bank make a credible commitment to maintaining a stable price level? Should monetary policy be used to reduce the tax on capital income? And would reducing uncertainty about inflation produce significant social benefits? Proponents

Stuck at zero: Price rigidity in a runaway inflation [PDF]

Economics Letters, 2021
We use micro level retail price data from convenience stores to study the link between 0-ending price points and price rigidity during a period of a runaway inflation, when the annual inflation rate was in the range of 60%-430%. Surprisingly, we find that 0-ending prices are less likely to adjust, and when they do adjust, the average adjustments are ...

Analysis of Longitudinal Binomial Data with Positive Association between the Number of Successes and the Number of Failures: An Application to Stock Instability Study

Entropy, 2022
Numerous methods have been developed for longitudinal binomial data in the literature. These traditional methods are reasonable for longitudinal binomial data with a negative association between the number of successes and the number of failures over ...

A comparison of statistical methods for modeling count data with an application to hospital length of stay

BMC Medical Research Methodology, 2022
Background Hospital length of stay (LOS) is a key indicator of hospital care management efficiency, cost of care, and hospital planning. Hospital LOS is often used as a measure of a post-medical procedure outcome, as a guide to the benefit of a treatment

Identifying Differentially Expressed Genes of Zero Inflated Single Cell RNA Sequencing Data Using Mixed Model Score Tests

Frontiers in Genetics, 2021
Single cell RNA sequencing (scRNA-seq) allows quantitative measurement and comparison of gene expression at the resolution of single cells. Ignoring the batch effects and zero inflation of scRNA-seq data, many proposed differentially expressed (DE ...

On the equivalence of one‐inflated zero‐truncated and zero‐truncated one‐inflated count data likelihoods [PDF]

Biometrical Journal, 2022
AbstractOne‐inflation in zero‐truncated count data has recently found considerable attention. There are currently two views in the literature. In the first approach, the untruncated model is considered as one‐inflated whereas in the second approach the truncated model is viewed as one‐inflated. Here, we show that both models have identical model spaces

Zero-inflated models and estimation in zero-inflated Poisson distribution

Communications in Statistics - Simulation and Computation, 2017
In this paper, we briefly overview different zero-inflated probability distributions. We compare the performance of the estimates of Poisson, Generalized Poisson, ZIP, ZIGP and ZINB models through Mean square error (MSE), bias and Standard error (SE) when the samples are generated from ZIP distribution.

PERFORMA PROPORSI ZERO-INFLATION PADA REGRESI ZERO-INFLATED NEGATIVE BINOMIAL (STUDI KASUS: DATA TETANUS NEONATORUM DI JAWA TIMUR)

E-Jurnal Matematika, 2018
Tetanus Neonatorum (TN) is an infectious disease that could be prevented by immunization. East Java Province is the highest numbers of TN case in Indonesia. TN data in East Java contain overdispersion and big proportion of zero-inflation (71,05%).

Generalized Sichel Distribution and Associated Inference [PDF]

Journal of Statistical Theory and Applications (JSTA), 2017
In this paper, we propose a generalized form of Sichel distribution which is obtained by mixing the Poisson distribution with the extended generalized inverse Gaussian distribution.
