Dear Statalist,

I hope this question is not too remedial.

I have an unbalanced panel of seven period and I would like to be able
to make a subset of a balanced panel.  I have created dummy variables
(T1-T7) for each of the time periods as well as a continuous variable
labeled time (1-7).  I would like to create another dummy variable to
use in the "if" qualifier of a regression which would be "balanced=1"
if there are observations in all 7 periods.

Any help would be greatly appreciated.

Thanks,
Jeremy
