Subject: st: xt unit-exclusive means by year
Dear statalist,
I'm trying to create an instrument in cross-sectional time series that takes
an initial value for each unit and then applies to it the mean trend for all
units but the one in question, and then repeats this operation for each
unit. Sounds simple, but I can't figure out how to do it: "by country:
egen instrument = mean(varname) if id ~= x" obviously doesn't work.
Interaction
expansion seems not to be the route. Do I have to program something? I'd
love not to have to create a new variable for each unit.
Thanks and best wishes,
Jim Mahon
