Hierarchical clustering in JMP - Finding inertia to determine cluster number
Oct 29, 2015 02:46 AM(3786 views)
Does anybody know if there is a way to get JMP to give you an interia plot or score when doing Hierarchical clustering? I would like to be able to use the value to determine the number of clusters to cut the dendogram at.
Whats usually called inertia for Ward's method is more or less plotted as "distance" at the bottom of the dendrogram. But you can obtain the Cubic Clustering Criterion in the "Cluster criterion" submenu of the platform : the minimum CCC computed value gives a good indication of the number of clusters to retain, at least if this minimum is clearly marked. The CCC was developed by SAS Institute in 1983 and you read all the details by downloading https://support.sas.com/documentation/onlinedoc/v82/techreport_a108.pdf.
