Several techniques to test for group differences in
weighted multidimensional scaling (MDS) subject
weights have recently been proposed. The present
study presents monte carlo results to evaluate the operating
characteristics of two of these with ALSCAL-derived
subject weights. The first uses the analysis of
angular variation (ANAVA) on raw subject weights. The
second applies the analysis of variance (ANOVA) to the
flattened subject weights generated by ALSCAL. The
ANOVA on flattened weights was less affected by the
presence of error and by distortions caused by
ALSCAL’S normalization routine than was the ANAVA.
