st: calculating group means

[Gayatri Koolwal <gbk5@cornell.edu>]

Hello,

I have a data set of individuals who belong to different households, each 
with a value of a variable x2.  For each household, I would like to create 
a new variable that is the mean of x2 for the individuals in that 
household.  Would anyone be able to help me with the procedure for 
this?  Do I need to collapse the data set first somehow?

Thank you very much!

Gayatri Koolwal.
