FORTRAN IV Program for Q-Mode Cluster Analysis of Nonquantitative Data using IBM 7090/7094 Computers

Abstract

CLUST3 is an IBM 7090/7094 FORTRAN IV program for classifying objects into groups based on a large number of nonquantitative characters considered simultaneously. Either Sokal and Michener's coefficient or Jaccard's coefficient may be used as a measure of similarity. The mean expected value of similarity also is calculated. The weighted or unweighted pair-group method may be used for clustering and results may be displayed automatically by setting a plotting option for drawing a dendrogram. A version for the IBM 360/67 also is obtainable from the Kansas Geological Survey.
