I'm using a dataset with "importance weights": frequency weights
multiplied by the sampling rate n/N -- so that the sum of those
importance weights equals the sample size n, not the target population
size N) and I'd like to do a Pearson chi-squared test on a 2-way
contingency table. It shouldn't be too hard, but the chi2 option of the
tab command doesn't accept iweights. Only integer frequency weights seem
to be allowed. I could very well use frequency weights instead, but that
would increase the Chi2 stat unreasonably.
Any idea on how to get round this problem?
Thanks a lot (and sorry if the question is too trivial!)
