Does anybody know of a Stata implementation of multi-level
zero-inflated Poisson regression that I might use for longitudinal
data with zero-inflated count outcomes?
In his Sage book "Fixed Effects Regression Modeks" Paul Allison says
(p. 68) "This chapter does not consider zero-inflated Poisson and
negative binomial models for 3 reasons: They are much more complex,
there is little software available for panel data, and, finally, the
negative binomial model itself often provides a satisfactory fit to
data with large numbers of zero counts."
