Definitions of parameters used in evaluating the predictions
Evaluation | Formula |
Sensitivity | TP/(TP + FN) |
Specificity | TN/(TN + FP) |
Accuracy | (TP + TN)/(TP + TN + FP + FN) |
Positive predictive value (PPV) | TP/(TP +FP) |
Overall performance (OP) | (Accuracy + PPV)/2 |
FN, false negative; FP, false positive; TN, true negatives; TP, true positives.
