In PROC HPCLUS, a data scientist wants SAS to automatically determine the optimal number of clusters. Which option enables this capability?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Here's the deal — b is correct because PROC HPCLUS can evaluate multiple values of k when MAXCLUSTERS= is specified, using internal cluster validity criteria such as the Cubic Clustering Criterion (CCC), pseudo F statistic, and pseudo t-squared to suggest the optimal k. A (CLUSTERS=AUTO) is not valid syntax.

Full Explanation
B is correct because PROC HPCLUS can evaluate multiple values of k when MAXCLUSTERS= is specified, using internal cluster validity criteria such as the Cubic Clustering Criterion (CCC), pseudo F statistic, and pseudo t-squared to suggest the optimal k. A (CLUSTERS=AUTO) is not valid syntax. C is wrong because automatic selection is supported via MAXCLUSTERS= and criteria output. D (AUTOCLUSTER=YES) is not a valid option.
