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.

Semiparametric zero-inflated Bernoulli regression with applications
Journal of Applied Statistics, 2021 When the observed proportion of zeros in a data set consisting of binary outcome data is larger than expected under a regular logistic regression model, it is frequently suggested to use a zero-inflated Bernoulli (ZIB) regression model. A spline-based ZIB regression model is proposed to describe the potentially nonlinear effect of a continuous ...

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

Deflating the Case for Zero Inflation
Quarterly Review, 1990 This paper analyzes the U.S. congressional proposal to instruct the Federal Reserve to, in the next five years, lower inflation to zero from its current rate of around 5 percent. The paper concludes that, when other policy options are considered, the zero inflation policy is not advisable.

Droplet scRNA-seq is not zero-inflated [PDF]
Nature Biotechnology, 2019 Potential users of single cell RNA-sequencing often encounter a choice between high-throughput droplet based methods and high sensitivity plate based methods. In particular there is a widespread belief that single-cell RNA-sequencing will often fail to generate measurements for particular gene, cell pairs due to molecular inefficiencies, causing data ...

Bayesian clustering of multiple zero-inflated outcomes
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2023 Several applications involving counts present a large proportion of zeros (excess-of-zeros data). A popular model for such data is the hurdle model, which explicitly models the probability of a zero count, while assuming a sampling distribution on the positive integers. We consider data from multiple count processes.

Approximation of Zero-Inflated Poisson Credibility Premium via Variational Bayes Approach
Risks, 2022 While both zero-inflation and the unobserved heterogeneity in risks are prevalent issues in modeling insurance claim counts, determination of Bayesian credibility premium of the claim counts with these features are often demanding due to high ...

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
