Dear sir I have use 2 method (class 1 and class 2) to compute sensitivity, Specificity and accuracy for 7 data set (D1-D7) how can i compute its AUC and how it can be plotted for ROC? Please help me. Your help would be much appreciated. Please see the data table below.
D1 D2 D3 D4 D5 D6 D7 Class 1 Sen 95.85 95.56 97.26 96.35 94.56 95.69 96.87 Spe 94.36 94.39 96.54 95.36 94.25 95.82 94.56 Acc 96.33 97.12 96.55 96.89 95.66 95.89 96.78 class 2 Sen 93.76 93.45 94.28 93.56 94.58 93.58 93.42 Spe 92.91 92.13 93.25 93.28 93.29 94.57 92.99 Acc 94.56 94.12 93.23 94.12 93.56 93.23 93.89
