Hi,
I try to understand what the error message printed below means, and what
to do.
In fact, I analyse a data set from the European Social Survey which is
provided with a weight variable /anweight /which I used.
I got the error message:
warning: FREQUENCIES: At least one case in the data file had a weight
value that was user-missing, system-missing, zero, or negative. These
case(s) were ignored.
1 | freq anweight.
| ^
A frequency output of anweight shows no user- or system-missing,
negative or zero value. For a multi-million representative and publicly
downloadable bi-annual population study this would be surprising.

Any ideas ?
