Definition
The Power Curve (also: Receiver Operating Characteristic) is a Visualization and quantification of model classification performance. The plot is simply a joint graph of correct classifications against incorrect classifications as a function of the classifier parameter (e.g., credit score).
Usage
The power curve provides a simple and comprehensive overview of overall model performance. It is easy to inspect whether there is significant success at classification (the curve slopes upward), but also to immediately get a sense of data quality.
