What are sensitivity and specificity?

Submitted by tgoswami on 03/23/2021 - 01:17

Specificity is the same as true negative rate, or it is equal to 1 – false positive rate. It tells you out of all the actual '0' labels, how many were correctly predicted.

Specificity = \frac{TN}{(TN + FP)}

Sensitivity is the true positive rate. It tells you out of all the actual '1' labels, how many were correctly predicted.

Sensitivity = \frac{TP}{TP + FN}
