The inputs must be vectors of equal length. tpr = tp / (tp + fn) fpr = fp / (fp + tn) tnr = tn / (tn + fp) fnr If your true positive rate is 0.25 it means that every time you call a positive, you have a probability of 0.75 of being wrong. This is your false positive rate. Similarly , True negative. When no attack has taken place and no alarm is raised, you have a true negative condition.
