NEW QUESTION 4

Which metric can you use to evaluate a classification model?

• A. true positive rate
• B. mean absolute error (MAE)
• C. coefficient of determination (R2)
• D. root mean squared error (RMSE)

Answer: A

Explanation:
What does a good model look like?
An ROC curve that approaches the top left corner with 100% true positive rate and 0% false positive rate will be the best model. A random model would display as a flat line from the bottom left to the top right corner. Worse than random would dip below the y=x line.
