[ncdcta00@uniroma2.it]

I wish you an happy new year.
I have a question about calculated a new variable that have the same  
value for all person in the house.
I have a datset where the variables are: hid(ident house),  
pid(personal ident), houseincome(income in the house), wagefemel(wage  
of wife)
and income( houseincome - wagefemel)

hid         pid        houseincome     wagefemal   income
1            1               100        0           100
1            2               100        10          90
1            3               100         0          100


I have need that the house income is the house income minus wagefemal  
for ech pid in the same house(hid) or 90.
I created wagefemal by hid, but not change.
thanks a lot for your help.
