receiver operating characteristic

(redirected from Receiver operator curve)

re·ceiv·er op·er·at·ing char·ac·ter·is·tic (ROC),

a plot of the sensitivity of a diagnostic test as a function of nonspecificity (one minus the specificity). The ROC curve indicates the intrinsic properties of a test's diagnostic performance and can be used to compare the relative merits of competing procedures.
