Subject | st: collapse with fweights |
Date | Wed, 31 Mar 2010 13:33:32 -0600 |
Hello all, I'm trying to collapse some very tall data, and I would like to operate on two varlists with the command: collapse (sum) vars1 (rawsum) vars2 [fw = fweight] The manual states that the computation of `rawsum' should ignore the specified weight, but I find that the sum this command puts out does not include any of the observations of vars2 for which fweight=0 , despite the (rawsum) specification. Is there any way to stop this behavior, or perhaps some better way to approach processing the data in this manner? Thanks for reading, any help is greatly appreciated.
