Thanks for your answers Joseph and Nick.
I have another problem. When I tried to run -xtgls- Stata saids:
insufficient memory for temporary matrix
You need to increase the size of memory; see help memory.
r(950);
In a previous ocassion I ran the same command in the same laptop, I
don't kwon what happens. Also, after I could assign more than 1gb to
memory (I have 3gb of RAM), but now I can only assing 500mb.... what's
going on?
