Dear all,

Apologies for the uninformative subject line but I couldnt think of a
way to easily describe my problem. I d like to create a variable that
takes as values the proportion of ones of another variable X when the
line under consideration is excluded. Specifically, I d like to have
the proportion of smokers in the household other than the individual
under consideration. Below is a table where proportion is the variable
I d like. pid is individual identifier, hid is household identifier, X
is an indicator with 1 if smoker 0 otherwise.

pid     hid     X       proportion
1       1       0       0
2       1       0       0
3       1       0       0
4       2       1       0
5       2       0       1
6       3       0       1
7       3       1       0.66
8       3       1       0.66
9       3       1       0.66
10      4       0       0.4
11      4       0       0.4
12      4       0       0.4
13      4       1       0.2
14      4       1       0.2
15      4       0       0.4


Any help is greatly appreciated.

Regards
Manos
