Greetings!
Is there anyway in Stata to run a 2 or more equation model? Basically,
I was wondering if there is anything that brings the reg3 command
together with the xt (especially the fixed effects) capabilities in
Stata. For example, I have tried using xtdata, fe and then the reg3
command, but I get an error saying covariance matrix of errors is
singular.
Any help would be greatly appreciated.
Cheers,
Cooper
