I finally get to chime in! Fairly new to the list (about a week), so here goes...

-findit _gwtmean-

Install this package, and you will have a new command, -wtmean-, that works as follows:

- egen newvar = wtmean(price), weight(quantity) -

Thanks to David Kantor for this code.

Take care,
Jared

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
