Dear statalisters,

I have longitudinal data where patients have information on several timepoints.
Some values from constant variables are missing. How should I fill in
these observations across the panel (pte id)?

Example:
pid  visit#  gender
1      1          1
1      2           .
1      3           .
1      4           1
2      1           .
2      2           .
2      3           0
2      4           .
etc..................

I did tried the ssc program "enlarge" but reported error when values
existed more than once (as in pte 1).

I would appreciate any help,

Eduardo
