Hello all,
I have :
id employ
1 2
2 1
3 2
3 2
4 2
4 1
5 1
5 2
6 1
6 1
where id= subject identification and employ=1 if the person is employed and employ=2 if the person
is unemployed.
I want to keep in the data those subjects whose are unemployed in the first observation (employ=2)
without losing their second observation if they are observed more than once, that is:
id employ
1 2
3 2
3 2
4 2
4 1
How can I do that?
Thanks,
Patricia
