After running PROC CLUSTER METHOD=WARD, a dendrogram is produced. Which PROC TREE option cuts the dendrogram at a specific number of clusters?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Here's the deal — d is correct because PROC TREE provides two complementary cutting approaches: NCLUS= specifies the number of clusters (cuts horizontally to produce exactly k clusters), and CUTVAL= specifies the linkage height threshold (cuts at a specific dissimilarity value). Both are valid options and serve different analytical needs.

Full Explanation
D is correct because PROC TREE provides two complementary cutting approaches: NCLUS= specifies the number of clusters (cuts horizontally to produce exactly k clusters), and CUTVAL= specifies the linkage height threshold (cuts at a specific dissimilarity value). Both are valid options and serve different analytical needs. A is correct alone but B is also correct, so D captures the full answer. C is wrong; HEIGHT= is not a PROC CLUSTER option for specifying cluster count.
