Critical points for certain statistical measures of agreement

This paper further explores the analytic connections between three commonly used statistical measures of agreement for 2 × 2 contingency tables: sensitivity, specificity, and the kappa coefficient, which are often employed in evaluating diagnostic tests. In particular, for a given fixed kappa the co...

Description
Summary:This paper further explores the analytic connections between three commonly used statistical measures of agreement for 2 × 2 contingency tables: sensitivity, specificity, and the kappa coefficient, which are often employed in evaluating diagnostic tests. In particular, for a given fixed kappa the corresponding locus of minimum values of sensitivity and specificity is rigorously derived.
