Waller, Niels G.; Underhill, J. Michael; Kaiser, Heather A. – Multivariate Behavioral Research, 1999
Presents a simple method for generating simulated plasmodes and artificial test clusters with user-defined shape, size, and orientation. For "J" clusters, indicator validity is defined as the squared correlation ratio between the cluster indicator and J-1 dummy variables. Illustrates the method through simulation. (SLD)
