Methodological study derives the mean and variance of kappa and weighted kappa statistics for independent raters, facilitating precise statistical inference in agreement studies.
This paper considers the mean and variance of the two statistics, kappa and weighted kappa, which are useful in measuring agreement between two raters, in the situation where they independently allocate a sample of subjects to a prearranged set of categories.
