Subject: xtreg
Catia said
I use the command xtreg but I have a problem when I
use the comand by country: xtreg,,,,,
make an error: insufficient observation, but if do the
sum of my var. I have observation.
Can help me please.
If your data have i = country and t = time, it makes no sense to
apply an 'xt' command by country, since that specifies a single
time series. Only if you have a more complex data structure--e.g.
firms within countries, with i = firm --- would this make sense.
What is your tsset? If it is tsset country year, e.g., you cannot
compute xtreg for each i.
