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
Here's the deal — you use NCLUS= in PROC TREE when you want the dendrogram cut into a specific number of clusters. It cuts horizontally to produce exactly that many clusters, while cutting by linkage distance is a different job.
Full Explanation
The correct choice is NCLUS= in PROC TREE, because it cuts the dendrogram into a requested number of clusters. PROC TREE also supports CUTVAL=, but that cuts at a linkage distance or height threshold, not by cluster count. OUTTREE= in PROC CLUSTER is wrong because it writes tree data for PROC TREE rather than producing a dendrogram already cut at a requested cluster count. HEIGHT= in PROC CLUSTER is wrong because it is not the PROC TREE option for specifying cluster count, nor a PROC CLUSTER option for specifying cluster count directly.
