Dear Statalisters,
Good day. I am currently using a legal copy of Stata 10. I wanna estimate a reduced form equilibrium model (with fixed effects) of real estate investments for 36 cities for 5 years. In the first column of my data file, I put Regions in the first cell, and then listed the cities one by one. Then I typed
xtset regions
The response is
varlist: regions: string variable not allowed
r(109);
However I can do the same thing with my friend's Stata 8.
I also try to do "xtset all variables" one by one. Then I typed
xtreg y x1 x2 x3 x4 x5, fe
The response is
insufficient observations
r(2001);
Is there anyone who can tell me how to fix this problems? Thank you in advance.
Best regards,
Winky
