A fraud dataset contains 99 percent legitimate transactions and 1 percent fraud. Why can accuracy alone be misleading?

Choose the Best Answer

Accuracy is used only for regression models. A model can predict every transaction as legitimate and still achieve very high accuracy while missing all fraud. High accuracy proves the model has high recall for fraud. Accuracy automatically penalizes missed fraud more than false alerts.
