I am working with Panel data information. I am trying to create a filter
to tell me Which individuals have complete information for a set of
variables AND just let me know which of them -individuals- have more than
certain amount of observations. For example if a have data for 10 years i
want stata to tell me which individuals have information of the variables
in the same years AND only let me know those individuals that have data
for more than 6 years.... Thanks for any pointers in the subject. As you
can see i am rather a neophyte in the subject. As far as I have gotten is:
by shcode: summarize reservas depeendencia if (reservas~=.) &
(dependencia~=.)
What i want to create is something like:
by shcode: summarize reservas depeendencia if (reservas~=.) &
(dependencia~=.) & (Number of Observations or periods in which i find
both "dependencia" and "reservas" or matching datas are more than 9 periods.
