The figure below depicts the decile-wise lift chart from the Beer Preference example discussed in class (for the validation data set). This is the logistic regression classification model with INCOME and AGE as the explanatory variables. Preference for Light beer is the success class. Which of the following most accurately describes performance in the fifth decile (in terms of the ability of the classifier to identify people with a preference for light beer)?

Question
The figure below depicts the decile-wise lift chart from the Beer Preference example discussed in
class (for the validation data set). This is the logistic regression classification model with INCOME
and AGE as the explanatory variables. Preference for Light beer is the success class. Which of the
following most accurately describes performance in the fifth decile (in terms of the ability of the
classifier to identify people with a preference for light beer)?
O
4
0 1 2 3
Decile wise comparision of successes
|||
1 2 3 4 5 6 7 8 9 10
Deciles
Performance of the classifier is around 50% worse than picking an equal size sample at random
Performance of the classifier is around 100% better than picking an equal size sample at random
Performance of the classifier is around 50% better than picking an equal size sample at random
The classifier performs no better than random.
O Performance of the classifier is around 50% better than picking from the lowest decile
