I have a dataset as follows:
hhid psid year
1 1 1989
1 1 1991
1 1 1993
1 1 2000
1 2 1989
1 2 1991
1 2 1993
1 2 2000
2 1 1989
2 1 1991
2 1 1993
2 1 2000
... ... ...
hhid=household ID
psid=personal ID within a household
And my question is how to create a personal ID (say
uid) applied to the whold panel dataset.
------------------------------------------
You could:
sort hhid psid year
egen uid=group(hhid psid)
Hope this helps
