|Subject: ||Kappa confidence intervals|
We are currently upgrading from SAS 8 to version 9. When re-running some
old programs under version 9 we noticed the following: The upper limit of
the confidence interval for the kappa statistic (calculated using Proc
FREQ) is now always bounded at 1. Previously under version 8 we had some
cases where the upper limit was slightly above 1 (say 1.0386).
I looked up "What's New in SAS 9.x" on the SAS Institutes web page but I
couldn't find anything that would explain this.
Does anyone know anything more about this?
