TWO ADDITIONS TO HIERARCHICAL CLUSTER ANALYSIS†
Gunnar T. Gruvaeus, Howard Wainer · British Journal of Mathematical and Statistical Psychology · 1972
Two additions to Johnson's hierarchical cluster analysis (1967) are proposed. The first is a procedure for ordering the clusters to make the obtained solution unique and frequently more meaningful. The second is a similarity measure, whereby two (or more) cluster solutions of the same set of variables can be compared. The value of ordered clusterings is illustrated with a reanalysis of data from Miller & Nicely (1955).
