Modelling Zero-Inflated Count Data When Exposure Varies : With an Application to Sick Leave

Baetschmann, Gregori; Winkelmann, Rainer - 2012

This paper is concerned with the analysis of zero-inflated count data when time of exposure varies. It proposes a new zero-inflated count data model that is based on two homogeneous Poisson processes and accounts for exposure time in a theory consistent way. The new model is used in an...

Count Models Based on Weibull Interarrival Times

Bradlow, Eric; Fader, Peter; Adrian, Moshe; McShane, Blake - 2012

The widespread popularity and use of both the Poisson and negative binomial models for count data arises, in part, from their derivation as the number of arrivals in a given time period assuming exponenitally distributed interarrival times (without and with heterogeneity in the underlying base...
