✦ Synopsis

The kappa index ie usually used for measuring the agreement between two observere when the scale ie nominal. A modifioation of Cohen's kappa index waa given by Krauth. The new estimator was biased and ita large sample variance was obtained. An alternative estimator is developed here It is a ratio eetimator and ita mean square error is derived. A comparison with Cohen's estimator and aauth's one ie given by the exemplea ueed in the paper of Krauth.

The intraclass correlation coefficient (r,) has been advocated as a statistic for assessing agreement or consistency between two methods of measurement, in conjunction with a significance test of the difference between means obtained by the two methods. We show that neither technique is appropriate
