Assessing similarity between profiles

Assessing similarity between profiles General methodological difficulties are discussed, particularly; the need to discuss similarity only with respect to specified dimensions, loss of information involved when configurations are reduced to indices, the need to interpret a similarity index as a relative rather than as an absolute measure, and the general non-comparability of scale units involved in profiles. The measure D is presented. This is, for two profiles, the sum of the squared deviations of corresponding scores, and is a general expression for dissimilarity (distance in the hyperspace of k variates). 27 references. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Psychological Bulletin American Psychological Association

Abstract

General methodological difficulties are discussed, particularly; the need to discuss similarity only with respect to specified dimensions, loss of information involved when configurations are reduced to indices, the need to interpret a similarity index as a relative rather than as an absolute measure, and the general non-comparability of scale units involved in profiles. The measure D is presented. This is, for two profiles, the sum of the squared deviations of corresponding scores, and is a general expression for dissimilarity (distance in the hyperspace of k variates). 27 references.
