Identifying a Migration Effect in Complete-Link Hierarchical Clustering

Journal of Educational and Behavioral Statistics, 1979, vol. 4, issue 1, 74-92

Abstract: The migration effect refers to a problem encountered in almost all hierarchical clustering schemes that build up a partition hierarchy in a sequential fashion. Specifically, the least refined partitions constructed by such methods have a tendency to “migrate†away from what could be considered more adequate decompositions of the object set being considered. This phenomenon is illustrated with respect to the well-known complete-link method. In addition, several procedures are suggested for identifying the presence of migration and/or for helping evaluate its severity.
