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
Here's the deal — PROC HPCLUS can search for the best number of clusters when you set MAXCLUSTERS= and let a criterion such as the Cubic Clustering Criterion choose the best value. It does not use a magic AUTO setting.
Full Explanation
The choice using MAXCLUSTERS= with a criterion like CCC 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. CLUSTERS=AUTO is not valid syntax. Saying the procedure cannot select k automatically is wrong because MAXCLUSTERS= and criteria output support it. AUTOCLUSTER=YES is not a valid option.
