Web4 Nov 2004 · These proportions are the sensitivity and 1 – specificity, respectively. A graph of sensitivity against 1 – specificity is called a receiver operating characteristic (ROC) curve. Figure 1 shows the ROC curve for lactate using the cut-off values given in Table 4. The preferred method is to join the points by straight lines but it is possible ... Web15 Jul 2024 · The ROC(receiver operating characteristic) curve is used with binary classifiers. It is very similar to the precision/recall curve, but instead of plotting precision versus recall, the ROC curve plots TPR(the true positive rate) versus FPR (false positive rate).
