Dear Statalisters,
I�ve got an unbalanced panel dataset covering 30 OECD-countries (i) over a
period of 15 years (t).
Running for example a fixed effects regression, I lose a lot of observations
due
to the missings in some of the variables (as I said, I�m dealing with an
unbalanced panel).
In some cases I only have about 50 observations left.
I've tried to figure out why this is the case, and I suspect that Stata uses
only those observations of one country where there are no missings in any of
the
variables X_i at time t.
Is there a way to some kind of "save on observations" i.e. tell stata to use
all
of the observations available irrespective of the fact that some of the
observations for a country i (panel) at time t are missing?
Any suggestions would be greatly appreciated.
Regards
Jessica
