Calculate AUC from ROC Curve

This function calculates the Area Under the Receiver Operating Characteristic (ROC) curve. It uses the trapezoidal rule to compute the AUC from the false positive rate (FPR) and sensitivity (true positive rate).

Usage

calculate_auroc(fpr, sensitivity)

Arguments

fpr

A numeric vector of false positive rates from the ROC curve.

sensitivity

A numeric vector of sensitivities (true positive rates) from the ROC curve.

Value

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