Hi Dennis -

I haven't heard of the Adjusted Rand Statistic, and a quick look through both the system help and the SAS manuals didn't net me anything.  Where do I find this creature?

Thanks, Deb

In this case you should not be using kappa, you should be using the Adjusted Rand Statistic that is designed for this exact situation.
