WebAUC - ROC Curve In classification, there are many different evaluation metrics. The most popular is accuracy, which measures how often the model is correct. This is a great metric because it is easy to understand and getting the most correct guesses is often desired. There are some cases where you might consider using another evaluation metric. http://www.rad.jhmi.edu/jeng/javarad/roc/JROCFITi.html
