Hello,
how does one program an HLM with a Probit to correct
for sample selection in STATA?
I need to estimate a Probit to model a decision (say,
whether to impose a new tax) then use the estimate
(based on the inverse Mill's ratio) to correct for
selection bias when estimating (say) separate
expenditure regressions for jurisdictions that choose
to impose the tax, and those that do not.
Any help would be appreciated,
thank you,
Hella
