Interpretation of Hierarchical Clustering
This paper deals with several questions which may arise in the user’s mind when using hierarchical cluster analysis. Having obtained a dendrogram from his or her data, the user would often like to have some help: if the dendrogram shows clear cut groups, he or she would like to know which variables are responsible for the existence of these groups, or which values of the variables are characteristic of the various groups. Another interesting matter would be : how well does the dendrogram fit the initial data ?
