Dear all
I wish to run a probit with potentially endogenous regressors (as the
selection model in the first stage of a heckman two-step estimation)
using ivprobit in Stata 8.2, but keep getting an error message.
this is an example of how I type the syntax:
ivprobit market irrig (areacrop=areatot), robust cluster(hh_id)
This is what stata tells me:
. unrecognized command: ivprobit
Am I doing something wrong? Is ivprobit actually available in 8.2?
Many thanks
Jennifer
