A

It indicates the limit beyond which a predictor is considered significant.

B

It measures the overall accuracy of the model.

C

It is the average value of all predictors combined.

D

It shows the correlation between two predictors.

Understanding the Answer

Let's break down why this is correct

Answer

In a statistical model the threshold value is the cut‑off you choose to decide whether a predictor’s output signals a positive outcome or not; it is the point at which you say “yes” or “no. ” Sensitivity, or true‑positive rate, measures how often the model correctly flags positives when the threshold is low, so lowering the threshold usually increases sensitivity but may also raise false positives. Conversely, raising the threshold reduces sensitivity because fewer cases are counted as positive. For example, in a medical test, if the threshold for a blood marker is set very low, the test will flag many patients as sick (high sensitivity) but may also incorrectly label healthy people as sick. Thus the threshold directly controls how sensitive the model is to detecting true positives.

Detailed Explanation

The threshold is a cutoff number. Other options are incorrect because People sometimes think the threshold tells how well the whole model works, but it only deals with individual predictors; Some think the threshold is the average of all predictors, but it is not a mean.
