< An ROC (receiver operating characteristic) curve plots the false positive rate (x-axis) against the true positive rate (y-axis) for different model thresholds. The graph below shows three different ROC curves labeled 1, 2, and 3. (Click the icon to view the pruned decision tree.) Requirements 1. Compare the curves labeled 1, 2, and 3 in the chart above. Which curve represents the model that would be most useful for a management accountant? Explain. 2. Explain what a "straight line" ROC curve actually represents. numb Requirement 1. Compare the curves labeled 1, 2, and 3 in the chart above. Which curve represents the model that would be most useful for a management accountant? Explain. all ight The more accurately a model predicts negative outcomes as negative outcomes and positive outcomes as positive outcomes, the closer the ROC curve will curve labeled Therefore, the ROC represents the model that would be most useful for a management accountant
