Dear all, I have a question on Cohen's kappa:
Assume I have two datasets, one has 500 objects, 10 methods and the other, 1000 different objects, 20 different methods. Could I compare between the two datasets to conclude the 10 methods are more "concordant" than the 20 ones by looking at some output, for example, cohen.kappa{concord} ? One more, could anyone explain in brief, what's the difference between kappa(Cohen) and kappa(Siegel)? Thanks, -- Weiwei Shi, Ph.D Research Scientist GeneGO, Inc. "Did you always know?"
