4/05 How do I create variables summarizing for each
individual properties of the other members of a
group?

Your problem is similar to that in Section 5, but the code can be
simplified a bit.
gen mymedian = .
bysort region : gen myid = _n
su myid, meanonly
quietly forvalues i = 1/`r(max)' {
egen work = median(y / (myid != `i')), by(region)
replace mymedian = work if myid == `i'
drop work
}
drop myid
