<prompt> Which of the following option is true about ROC curve?It is a method of evaluating the qualityperformance of testsIt is plotted as test Sensitivity as x-coordinate versus its 1-Specificity False positive rate FPR as the y-coordinateA perfect test has an area under the ROC curve AUROCC of 1A decrease in sensitivity result in decrease in specificity  <response>: ROC curve Recicver. Operator characteristic curve. 1 - No use 2 - fair 3 - Good 4 - Excellent Area under the ROC cure 1 - if specificity and sensitivity both are 100 ROC curve - it is a method of evaluating the quality performance of tests.
