Dear all,
I have time series-cross-section (TSCS) count data with a large number of z=
eros. I am currently estimating my models using -xtnbreg- and -xtpoisson-.=
I am interested in exploring whether it makes sense to separately model t=
he zero-generating process, and I would like to estimate the model using a =
zero-inflated model, using either the -zip- or -zinb- commands. I am unabl=
e to find an -xt- version of either estimation routine. Is anyone aware of=
any user-written add-ons, or of any other acceptable way to adopt the zero=
-inflated methodology to panel data?
