Hello
I've been using the command stir (incidence rate comparison). The manual says that stir allows iweights and fweights (more specifically it says you can specify stset with iweights and fweights), but when I use iweights I get an error message saying the iweights are not allowed. Is it a known issue? Is there a particular reason for the command to prevent weighting data with iweight or is it a bug? I know that some commands do not allow the use of all types of weights. But stip, a similar command which make similar calculations but do not report confidence intervals, does not forbid the use of iweights.
Thanks for your help
