I doubt there is much call for an nw option (naive weight)? But
otherwise for some analysis one is reduced to multiplying and/or
rounding off weights to get the point estimates that the data
depositors/creators tell you that you should be getting (i.e. the ones
in their report). Such as:
I would suggest that if you have to round off the weights (along with
possibly multiplying them by something first) to match something in a
report, then the people who did the calculations behind the report did
something incorrect. That Stata doesn't automatically reproduce that
incorrectness is reassuring to me.
