The Recovery of Structure in Linear and Ordinal Data: INDSCAL versus ALSCAL.

Weinberg, Sharon L.; Menil, Violeta C.

Multivariate Behavioral Research, v28 n2 p215-33 1993

The ability of 3-way INDSCAL and ALSCAL models to recover true structure in proximity data based on 2-dimensional configurations varying in number of subjects (15 and 20) and stimuli, amount of error, and monotonic transformation is examined. INDSCAL outperformed metric and nonmetric ALSCAL in all conditions. (SLD)
