Is it possible to apply hurdle models (like the Craggit, probit and truncated models) to panel data, preferably with fixed effects to control for unobserved heterogeneity?
In Stata, the user-written command craggit
only allows to use pooled panel data, but not to control for unobserved heterogeneity...
In general, the hurdle model is quite simple to estimate: probit model on the binary outcome variable, truncated (or lognormal) on the (positive values of the) outcome variable.
Is it possible to just estimate a RE probit (or even FE logit) in a first step, and a fixed effects model in the second – and to actually call that a hurdle model?
Thanks.
