Just out of curiosity: What do "RTFM" and "FWIW" stand for? Should we have a
repository of "frequently used abbreviations" in the list FAQ?

Subject: st: Poststratification weights
In the Stata svy commands, what is the difference between creating your
own poststratification weight (e.g. using -survwgt-) and treating it as a
pweight (through -svyset [pw=x], strata(y)-) vs. telling Stata
(through -svyset, poststrata(y) postweight(z)-) that you have a
postratification variable and cell count? This shouldn't affect point
estimates, but how does Stata treat the two differently with respect to
variance calculations or anything else? Thanks. (I would RTFM if I had
access to one, and I didn't find a FAQ or any discussion on the topic. I
am using Stata 9.2, FWIW.)
Michael
