within ID. If ID corresponds to a person then, barring gender reassignment
surgery, sex should be constant throughout an ID.

Subject: st: Missing Data
Dear Stata users,
Currently I am working on a data set where I have to fill the gaps in
the data and then
do analysis. An example of the data is as follows:

where for sex 1 is coded for males and 2 for females and for
employment status
(empstatus) 1 is employed and 2 for unemployed. Is there any fancy
command in stata
which can fill the gaps.
