Calculate AUC from Precision-Recall Curve

This function calculates the Area Under the Precision-Recall Curve (AUPRC). It uses the trapezoidal rule to compute the AUPRC from the recall and precision values.

Usage

calculate_auprc(recall, precision)

Arguments

recall

A numeric vector of recall values (sensitivity) from the precision-recall curve.

precision

A numeric vector of precision values from the precision-recall curve.

Value

The AUPRC score, a numeric value between 0 and 1.
