If only the customers in the top decile are selected, what percentage would actually default? 30% 50% 60% 100% c 2. Starting with the fewest customers at the top and increasing the number of cases, the classification performs better than random selection. What is fewest number of cases (other than zero) where the classification model has the same performance as random selection? 15 27 32 50 b 3. For a particular number of cases taken from the top of the list, the "lift" of the classification model can be measured by the number of actual Class 1 cases divided by the expected number of Class 1 cases in a random sample. What is the lift of the classification model for 20 cases? 10. 1.4 4.4 6.0 b
