Coefficient Kappa: Some Uses, Misuses, and Alternatives.

Peer reviewed

Brennan, Robert L.; Prediger, Dale J. – Educational and Psychological Measurement, 1981

This paper considers some appropriate and inappropriate uses of coefficient kappa and alternative kappa-like statistics. Discussion is restricted to the descriptive characteristics of these statistics for measuring agreement with categorical data in studies of reliability and validity. (Author)

An Investigation of Classification Consistency Indexes Estimated under Alternative Strong True Score Models.

Peer reviewed

Hanson, Bradley A.; Brennan, Robert L. – Journal of Educational Measurement, 1990

Using several data sets, the relative performance of the beta binomial model and two more general strong true score models in estimating several indices of classification consistency is examined. It appears that the beta binomial model can provide inadequate fits to raw score distributions compared to more general models. (TJH)
