An extension of the Random Error Coefficient of Agreement to N x N tables
CL Janes
Maxwell has proposed the Random Error Coefficient of Agreement (RE), as a
measure of agreement for the binary case based upon the assumption of
random distribution of questionable cases. The present paper presents a
more general formula for RE's computation and shows how the new form is
applicable to cases with more than two response categories.
