Hierarchical Clustering and the Concept of Space Distortion.
Hubert, Lawrence; Schultz, James
An empirical assesssment of the space distortion properties of two prototypic hierarchical clustering procedures is given in terms of an occupancy model developed from combinatorics. Using one simple example, the single-link and complete-link clustering strategies now in common use in the behavioral sciences are empirically shown to be space contracting and space dilating, respectively. An extension to an intermediate r-diameter clustering criterion defined in between the complete-link and single-link extremes is discussed briefly along with a technique for preprocessing the original proximity measures to make the results obtained from these two extreme clustering procedures more consistent with the data.
