Subject | st: EGEN GROUP where order doesn't matter? |
Date | Fri, 11 Feb 2011 15:11:31 -0500 |
Hi all, I understand that egen id=group(id1 id2) will create a list such that the pair (id1.1 id2.1)=1, (id1.2 id2.2)=2 etc. But, the order of the pair (id1 id2) matters so that the pair (id1.1 id2.1) will not yield the same value as (id2.1 id1.1). How can i make it so that the same value is generated, regardless of the varlist order?
