Hello ;
I am working on a problem where the dependent variable (iscloed) is binary and one of the regressors (isgroupon) is binary and endogenous.
Based on advice i got from the statalist, it was suggested to use a biprobit,
I ended up using something of the form
biprobit (isclosed = myfailpricerisk lreviewnumber isgroupon) (isgroupon = mygrouponziprisk mygrouponpricerisk lbrate)
A couple of questions :
1) Is the biprobit the correct command?
2) how do i get the marginal effect of "isgroupon" on "iscolosed" ?
Thanks
Ayman
