Re: st: Weighted mean of prices with quantities as weight

[Jared Delisle <rjd1867@fsu.edu>]

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
