st: RE: AW: SUREG by year
Thanks for the comment. I had already had a look at -help constraint- but I can´t see what I am looking for. How can I say Stata to take a different year for each equation in SUREG? How to perform the "constancy restriction"? maybe if I use isure as an option?
Thanks again,
Valeriano.

Betreff: st: SUREG by year
Dear all,
I want to run a SUR regression for a system of equations. I have the same
equation for different years and I want equal coefficients for all
regressors except for the incercept that will be year-specific.
I have a panel dataset, do I have to rename Y and X´s for each year
differently in order to run SUR? What is the correct syntax for the model
and the "constancy restriction"?
Any comment will be highly appreciated. Thank you very much,
Valeriano.
