good morning,
at least without seeing the data, i can speculate that this seems rather
complicated to me.
if you have data like these
family sib age
1 1 4
1 2 7
2 1 8
2 2 9
in that case , you could do the following
bys family (age): gen sibage=age[2] if _n==1
bys family (age): gen sibage=age[1] if _n==2
you could collapse this down to one line
bys family (age): gen sibage=(age[2]*( _n==1)+age[1]*( _n==2))
if you had more than two sibs per family, i would probably work with
-reshape-
(especially if you had varying numbers of kids in the family)
is this not what you wanted to do?
