receiver operating characteristic (roc) curve

How is an ROC Curve Constructed?

To construct an ROC curve, follow these steps:
1. Calculate Sensitivity and Specificity: For each possible threshold, calculate the sensitivity and specificity.
2. Plot the Points: Plot the sensitivity (y-axis) against 1-specificity (x-axis) for each threshold.
3. Connect the Points: Connect the plotted points to form a curve.
