In hierarchical clustering with PROC CLUSTER METHOD=COMPLETE, how is the between-cluster distance defined?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Here's the deal — c is correct because complete linkage defines between-cluster distance as the maximum distance between any pair of observations from different clusters (the furthest neighbors). A describes average linkage (METHOD=AVERAGE).

C is correct because complete linkage defines between-cluster distance as the maximum distance between any pair of observations from different clusters (the furthest neighbors). A describes average linkage (METHOD=AVERAGE). B describes single linkage (METHOD=SINGLE). D describes Ward's method (METHOD=WARD).
