st: egen "mean weight"

["Jorge Tuesta" <jtuesta@grade.org.pe>]

Dear statalisters,

Is it posible to create a average weight variable using "egen"?

I normally write:

egen mwage=mean(wage), by(iid)

but i would like "mean weight" (using [fweight=pop], for example) not 
simple mean. Is it posible?

Thanks in advance!

Jorge
