st: Weighted mean of prices with quantities as weight

["Beatrice Crozza" <beatrice.crozza@gmail.com>]

Dear all,

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?

Thank you very much.

Best,
Bea
