What is ROC used for?
ROC curves are frequently used to show in a graphical way the connection/trade-off between clinical sensitivity and specificity for every possible cut-off for a test or a combination of tests. In addition the area under the ROC curve gives an idea about the benefit of using the test(s) in question.
What is a good ROC?
What is the value of the area under the roc curve (AUC) to conclude that a classifier is excellent? The AUC value lies between 0.5 to 1 where 0.5 denotes a bad classifer and 1 denotes an excellent classifier.
Why ROC is required?

What is the difference between ROC and AUC?
AUC – ROC curve is a performance measurement for the classification problems at various threshold settings. ROC is a probability curve and AUC represents the degree or measure of separability. By analogy, the Higher the AUC, the better the model is at distinguishing between patients with the disease and no disease.
How ROC is calculated?
An ROC curve shows the relationship between clinical sensitivity and specificity for every possible cut-off. The x-axis showing 1 – specificity (= false positive fraction = FP/(FP+TN)) The y-axis showing sensitivity (= true positive fraction = TP/(TP+FN))
What is a good ROC AUC value?
AREA UNDER THE ROC CURVE In general, an AUC of 0.5 suggests no discrimination (i.e., ability to diagnose patients with and without the disease or condition based on the test), 0.7 to 0.8 is considered acceptable, 0.8 to 0.9 is considered excellent, and more than 0.9 is considered outstanding.
