title: Analyzing the performance of diagnostic tests.
abstract: When a single diagnostic test is used to assess the disease state of a patient, the classic univariate measures of sensitivity and specificity are used. When combining two or more diagnostic tests, other methods provide alternative methods for assessing the utility of combining these tests. We have written and tested a program in FORTRAN that computes the univariate statistics and bivariate concordant/discordant statistics analyses of all possible combinations of diagnostic tests as compared with the 'gold standard'.
