The ROC curve analysis technique can be of use even here. The Plot In order to draw the ROC curve, the concepts of ‘Sensitivity’ and ‘Specificity’ are used – the curve actually is the plot of sensitivity (in the y axis) against 1- specificity (in the x axis) for different ...
ROC also gives a numerical representation of the classifier performance when providing the “area under the curve” (AUC) value. An AUC of 0.5 corresponds to no classification power at all, and an AUC value of 1 denotes a perfect biomarker. In addition to a p-value and an AUC ...
ROC CurveThe ROC Curve option is available only for categorical responses. Receiver Operating Characteristic (ROC) curves display the efficiency of a model’s fitted probabilities in sorting the response levels. An introduction to ROC curves is found in ROC Curves in the Basic Analysis book....
