Thank you Jeff!
It works now.
However, I now get the following error message (using the -noisily- option):
- insufficient observations
an error occurred when bootstrap executed xtreg, posting missing values -
If this thread is correct
(http://www.stata.com/statalist/archive/2011-05/msg00732.html) then
it might be that there are not enough degrees of freedom for fixed effects
and clustered standard errors.
Well, -xtreg, fe vce(cluster ...)- works fine. Only when I use bootstrapping
the error message occurs.
Does bootstrapping need more degrees of freedom than the regular fixed
effects estimation or did I overlook something else?
Thanks,
Tobias
