Classifier Method for Positive Class

• A single class referred to as the Positive class (correct)
• The majority class in the dataset
• All classes in the dataset
• The class with the highest probability estimate

• To evaluate the performance of the classification method
• To identify the most common class label
• To assign a class label to each example
• To draw a lift curve and compare it to the random line (correct)

• By plotting the probability estimate against the class label
• By comparing the probability estimate of each example to the random line
• By dividing the ranked examples into several bins and counting the actual Positive examples in each bin (correct)
• By calculating the accuracy of the classification method
