Abstract
An approach for the investigation and comparison of the data structure in the multidimensional space is proposed. It is based on three prope rties, namely, the direction of the data sets, the variance-covariance of the data points, and the location of the data sets' centroids. A n umber of tests have been studied and are presented. It is shown that t he combined use of these parameters allows a satisfactory estimation o f the representativity between two data sets. Simulated data, as well as real case studies are presented. (C) 1998 Elsevier Science B.V. All rights reserved.
