I call this class of problems "everybody else" problems. 

I suggest starting with 

How do I create variables summarizing for each individual 
properties of the other members of a group?
http://www.stata.com/support/faqs/data/members.html

Note that means are easy, by virtue of 

sum of the others = sum of all - this value

after which 

mean of the others = sum of the others / (#values - 1)

Some of the other "everybody else" problems are 
a fair bit nastier than that.

With the looping I intend to generate peer-group variables ( means) using a PISA-like dataset ( with info on same school (peers)) for each pupil separately, but the observation (pupil) itself left-out (dropped) since otherwise it would not be a peer-group. In case you are interesetd in helping / willing to help me to find a more efficient way to do that, pls tell me.
