There is an FAQ
How do I create variables summarizing for each individual
properties of the other members of a group?
at
http://www.stata.com/support/faqs/data/members.html
which discusses this problem as well as others
in this territory. One broader context, of becoming
more familiar with the range of functions, is
written up in Stata Journal 2(4):411--427 (2002).
