Table 3 ROC
true positives | correctly identified true edges | tp |
|---|---|---|
false positives | spurious edges | fp |
true negatives | correctly identified zero edges | tn |
false negatives | unrecognized true edges | fn |
positives | all true edges | p = tp + fn |
negatives | all zero edges | n = tn + fp |
false positive rate | part of negatives set positive | fpr = fp/n |
true positive rate | part of positives set positive | tpr = tp/p |
false negative rate | part of positives set negative | fnr = fn/p |
true negative rate | part of negatives set negative | tnr = tn/n |
recall (sensitivity) | true positive rate | tpr |
specificity | true negative rate | tnr |
precision | positive predictive value | tp/(tp + fp) |
