The Doubly Inflated Poisson and Related Regression Models
… a seminal paper Lambert (1992) introduced Zero-Inflated Poisson (ZIP) model, which is a mixture model that accounts for the inflated zeros. In this thesis, two Doubly Inflated Poisson (DIP) probability models, DIP (<em>p</em>, λ) and DIP (<em> p</em>1, <em>p</em>2, λ), are discussed for …

Bivariate Doubly Inflated Poisson and Related Regression Models
… appropriate model for such data is the bivariate Poisson distribution given in Kocherlakota and Kocherlakota (2001). However, in situations where inflated count of (0, 0) occur, Lee et al. (2009) proposed the zero-inflated bivariate Poisson distribution which accounts for the inflated count. In …
