From: Preliminary study for non – invasive optical detection of squamous and basal cell carcinomas
Statistic Item | Result | Notes |
True positive (TP) | 36 | 72% of all 50 cases |
False positive (FP) | 5 | 10% of all 50 cases |
True negative (TN) | 9 | 18% of all 50 cases |
False negative (FN) | Zero | 0.00% of all 50 cases |
Specificity (TNR) | 64.62% | = TN/(TN+FP) |
Sensitivity (TPR) | 100% | = TP/(TP+FN) |
The positive prediction value (PPV) the proportion of true positives out of all positive results | 87.8% | = TP/(TP+FP) |
The Negative prediction value (NPV) the proportion of true positives out of all positive results | 100% | = TN/(TN+FN) |
Accuracy of our predictive measurements (ACC) | 90% | ACC= (TP+TN)/(P+N) Where; P = (TP+FN) N = (FP+TN) |
