Options:

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

Clustering the levels using the zip_code values as input.

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

Clustering the levels using dummy coded zip_code levels as inputs.

To provide an unbiased measure of assessment for the final model.

To compare models and select and fine-tune the final model.
