Example:
Suppose you have data for individuals, and also know which household
they belong to, and the age of each person in the household. You want to
attribute to each person the mean age among the individuals of the
household to which he belongs.
by hh_id: egen mean_age = mean(age)
More generally, look through -egen- in the manual; read about "by group"
operations in the User Guide, and also look through the Stata FAQs
