SAS Exam A00-240 Topic 4 Question 80 Discussion

Actual exam question for SAS's A00-240 exam

Question #: 80
Topic #: 4

An analyst knows that the categorical predictor, zip_code, is an important predictor of a binary target. However, zip_code has too many levels to be a feasible predictor in a model. The analyst uses PROC CLUSTER to implement Greenacre's method to reduce the number of categorical levels.

What is the correct application of Greenacre's method in this situation?

AClustering the levels using the target proportion for each zip_code as input.

BClustering the levels using the zip_code values as input.

CClustering the levels using the number of cases in each zip_code as input.

DClustering the levels using dummy coded zip_code levels as inputs.

Clustering the levels using the zip_code values as input? That's a bold move, Cotton. Let's see if it pays off.

I'm not sure, but I think C) Clustering the levels using the number of cases in each zip_code as input could also be a valid approach.

Hmm, I think option A is the way to go. Using the target proportion for each zip_code as input seems like the most logical approach to cluster the levels.

I agree with Layla, A) makes more sense because we want to reduce the number of levels based on the target variable.
