Abstract
The present example illustrates a method for assessing pattern similar ity for correlation matrices from populations known to differ in clini cally important respects. The data underlying previously published con firmatory factor analyses of neuropsychological traits are presented i n two methods for assessing whether the matrices are similar enough to justify their aggregation into a single composite matrix. The signifi cance of this procedure for research in applied neuropsychology is com mented upon in terms of the benefits to model diagnostics.
