aggregate group minus me

Andra Th

Dear list, 

I am trying to aggregate some variables measured at the individual level to the group level of analysis. Say I have satisfaction of person X and I want to aggregate the satisfaction of all N persons in group j to obtain the group level satisfaction. 
This, of course, is straightforward in SPSS. But I want to calculate this group score minus the score of the person for which the aggregation is conducted. So, person X will be assigned the group average score obtained by aggregating the score of all the persons in the group minus the score of the focal person X. 
I'd appreciate some syntax code to carry out this aggregation.

Re: aggregate group minus me

Dr Chris Stride

I assume you mean the mean score when you say aggregate?

If so, create the sum for each group and the N for each group (NG) using the aggregate command, then for each person, subtract their score from the sum and divide that by (NG - 1).


aggregate outfile = * mode = addvariable /break = groupid  /sumsat = sum(jobsat) /NG = N.

compute aggsat = (sumsat - jobsat)/(NG - 1).
exe.

Thank you, yes, I meant the mean and that worked perfectly!
