        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 would like to construct a weighted mean of prices, taking as weight
the quantity for each price.

I am using the command egen(mean)

How can I instruct Stata to use quantities for each price as weight?
