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