Definition
The area under curve (AUC) statistic is an empirical measure of classification performance based on the area under an ROC curve. It evaluates the performance of a scoring classifier on a test set, but ignores the magnitude of the scores and only takes their rank order into account. AUC is expressed on a scale of 0 to 1, where 0 means that all negatives are ranked before all positives, and 1 means that all positives are ranked before all negatives. See ROC Analysis.
