This is a FAQ. See FAQ . . Creating variables recording prop. of the other members of a group 4/05 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 The key principle for sums is elementary Sum of others = Sum of all - This value And for means correspondingly Mean of others = (Sum of all - This value) / (Number in group - 1) Other summary measures are more challenging, but the FAQ gives advice. The only obvious complication is that you want to sum across variables before you summarize across the other members of this group. That will often be easiest through -egen, rowtotal()-. Nick n.j.cox@durham.ac.uk Chao Yawo I am examining the effect of stigmatizing attitudes of specific health behaviors, using a demographic health survey (DHS). DHS respondents were required to indicate (by a YES, NO, DONT KNOW) whether: (1) whether they would buy a vegetable from a vendor who has HIV, (2) whether they would keep their family member's HIV infection a secret (3) whether they would be willing to care for a relative who is infected with HIV (4) wheether a female teacher infected with HIV should be allowed to continue teaching in school I want to calculate a summary score that reflects community attitude (the attitudes of all members of the community on these variables --- that is the score must EXCLUDE those of the respondent, and INCLUDE those of all others. In some literature, this is referred to as non-self mean. Since in the DHS, clusters (V022) are the lowest level from which a sample of households is drawn (i.e. these are typically the primary sampling unit), I want a score based on the responses of all people in the same strata (PSU) as the respondent, but excluding the respondent's responses. For example, to compute this score for an individual A who resides in PSU B, we sum the stigma scores (over all the 4 variables) of all individuals in PSU B, with the exceptoin of respondent A. I would be very grateful if you could give me some pointers about how to create this summary score (over all the 4 variables). regards, C.
