1/03 I want to calculate a variable containing weighted
group summary statistics, but I do not want to
collapse the data and egen does not support weights.
How can I do this?

I have to create a variable that compute the mean of varname (y) for a
particular area (area=1)and conditioned to an other variable (x, that
assumes value equals to 1,2,3,4,6),so I would calculate the mean of
y|x=1 in area=1, the mean of y|x=2 in area=1, and so on. I typed
egen mean=mean(y) if area==1, by (x)
but I have to introduce aweight to this computation, how can I do?
