Evaluation measures

See also Wikipedia

TP = True Positives, TN = True Negatives, FP = False Positives, FN = False Negatives

Sensitivity (Recall) = TP/(TP+FN)

Specificity = TN/(TN+FP)

Positive Predictive Value (Precision) = TP/(TP+FP)

F-measure = 2 x Precision x Recall / (Precision + Recall)

Correlation Coefficient (cc) = (TP x TN - FP x FN) / ((TP + FP) x (FP + TN) x (TN + FN) + (FN + TP))0.5
