Consider the following dataset of predicted scores and actual target values (you can assume higher scores should be assigned to the goods).

• Calculate the classification accuracy, sensitivity, and specificity for a classification cutoff of 205.

• Draw the ROC curve. How would you estimate the area under the ROC curve?

• Draw the CAP curve and estimate the AR.

• Draw the lift curve. What is the top decile lift?
