Question
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?
Options
- 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.
