What is False Positive Rate & False-negative Rate?

False Positive Rate:

• The false positive rate (FPR) is calculated as the number of incorrect positive predictions divided by the total number of negatives.

• The best false positive rate is 0.0, whereas the worst is 1.0. It can also be calculated as 1 – specificity.

$$SN = TP / TP*FN = TP / P$$

False Negative Rate:

• The false negative rate (FPR) is calculated as the number of incorrect positive predictions divided by the total number of positives.

• The best false negative rate is 0.0, whereas the worst is 1.0.
