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,
