摘要
We introduce a sequence of parameters called canonical moments to characterize the predictive value of the pattern of consensus among (k - 1) ratings to an additional rating. The usual kappa coefficient of agreement among ratings (two or more) is just the second canonical moment. By using the higher canonical moments, we can evaluate the consensus of multiple binary ratings.
