The equivalence of three statistical packages for performing hierarchical cluster analysis

  • Roger Blashfield
Notes And Comments


Three different software programs which contain hierarchical agglomerative cluster analysis procedures were shown to generate different solutions on the same data set using apparently the same options. The basis for the differences in the solutions was the formulae used to calculate Euclidean distance. Users of statistical software were warned of terminological confusion concerning cluster analysis.
