What is the True Negative Rate?
The True Negative Rate (Specificity, Selectivity) is a performance metric that measures the probability that your model will predict negative when the true value is negative.
- It is closely related to the True Positive Rate, which is completely analogous.
- The False Positive Rate and the True Negative Rate sum up to 1.
- The True Negative Rate is the answer to the following question: “If the true value is negative, what share did my model predict correctly?”
- The True Negative Rate is calculated as follows:
