Weighted Kappa Program

Hi all!

We need to run kappa on data with 16 categories. The program we currently use can only go up to 9...do any of you know of weighted kappa programs that can run with 16 categories?

Thank you!

R has several kappa functions in various packages; I don't know how they compare to each other or to the software you're using, but looking at the documentation it doesn't look like they have category limits. See the functions "kappa2" in irr, "wkappa" in psy, and "Kappa" in vcd.
I was just doing some (unweighted) kappas the other day in SAS, I didn't notice any limitation on categories in the documentation (it's been awhile...).
thanks very much to both of you - very helpful! I'll edit and tag this when we figure out for sure what worked for us :)
