A hierarchical finite mixture model that accommodates zero-inflated counts, non-independence, and heterogeneity.
A number of mixture modeling approaches assume both normality and independent observations. However, these two assumptions are at odds with the reality of many data sets, which are often characterized by an abundance of zero-valued or highly skewed observations as well as observations from biologically related (i.e., non-independent) subjects. We present here a finite mixture model with a zero-...
متن کاملExplaining Heterogeneity in Risk Preferences Using a Finite Mixture Model
This paper studies the effect of the space (distance) between lotteries' outcomes on risk-taking behavior and the shape of estimated utility and probability weighting functions. Previously investigated experimental data shows a significant space effect in the gain domain. As compared to low spaced lotteries, high spaced lotteries are associated with higher risk aversion for high probabilities o...
متن کاملZero-inflated Poisson regression mixture model
Excess zeros and overdispersion are commonly encountered phenomena that limit the use of traditional Poisson regression models for modeling count data. The focus of this paper is on modeling count data in the case that a population has excess zero counts and also consists of several sub-populations in the non-zero counts. The proposed zero-inflated Poisson regression mixture model accounts for ...
متن کاملFinite Mixture, Zero-inflated Poisson and Hurdle models with application to SIDS
This study examines the incidence of sudden infant death syndrome (SIDS) in Canterbury (1973–1989) in relation to climate. Three mixture models (Finite Mixture, Zero-in)ated Poisson and Hurdle) are used as novel methods which are able to highlight di8erential e8ects of climatic covariates between months of SIDS and no SIDS. These methods accommodate the extra zeros, heterogeneity and autocorrel...
متن کاملThe LZIP: A Bayesian latent factor model for correlated zero-inflated counts.
Motivated by a study of molecular differences among breast cancer patients, we develop a Bayesian latent factor zero-inflated Poisson (LZIP) model for the analysis of correlated zero-inflated counts. The responses are modeled as independent zero-inflated Poisson distributions conditional on a set of subject-specific latent factors. For each outcome, we express the LZIP model as a function of tw...
