The Fit of MDS and Unfolding Solutions
Ways to assess the goodness of an MDS solution are discussed. The Stress measure is defined as an index that aggregates representation errors. Criteria for evaluating Stress are presented. Stress per Point (SPP) is defined as a way to assess the fit of single points.
