| Abstract: | 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. |
