Hi,
in Stata/MP 12.1 I am getting missing values with using -pwcorr- with
-fweights- though the feature works fine with other data or if I scale
my weights down. Is it possible to simply have too large fweights,
e.g. if they cannot be of type -long- anymore?

If so, why doesn't Stata warn me about this?

I vaguely remember some Statalist of Stata blog discussion of this,
but I could not even Google it up, and Stata still did not warn me…

Actually, why didn't Stata complain that I did not have integer
fweights if obviously the variable wasn't of type byte, int or long?

Thanks,

Laszlo
