A Generalization of Cohen's Kappa Agreement Measure to Interval Measurement and Multiple Raters.
Berry, Kenneth J.; Mielke, Paul W., Jr.
Educational and Psychological Measurement, v48 n4 p921-33 Win 1988
Cohen's kappa statistic is frequently used to measure agreement between two observers using categorical polytomies. Cohen's statistic is: shown to be inherently multivariate in nature; expanded to analyze ordinal and interval data; and extended to over two observers. A non-asymptotic test of significance is provided for the generalized statistic. (Author/TJH)
