Use this option to perform hierarchical clustering via PROC CLUSTER.The computed distance matrix (or the Input SAS Data Set if it is already in the form of a distance matrix) is used as input to the CLUSTER procedure for clustering based on the chosen Distance Metric.Output of this option includes Diagnostic plots from PROC CLUSTER as well as a Dendrogram (or tree diagram) in HTML format.Caution: The CLUSTER procedure might result in longer run times because the CPU time is approximately proportional to the square or cube of the number of observations.Refer to the SAS PROC CLUSTER documentation for more information.
