Peer reviewedKarpman, Mitch – Educational and Psychological Measurement, 1979
This program calculates the chi-square statistic for testing the assumptions of equality and symmetry of covariance matrices in a repeated measures design. (Author)

Peer reviewedBolt, Daniel M. – Applied Psychological Measurement, 2001
Presents a new nonparametric method for constructing a spatial representation of multidimensional test structure, the Conditional Covariance-based SCALing (CCSCAL) method. Describes an index to measure the accuracy of the representation. Uses simulation and real-life data analyses to show that the method provides a suitable approximation to…

Peer reviewedSteiger, James H. – Educational and Psychological Measurement, 1979
The program presented computes a chi-square statistic for testing pattern hypotheses on correlation matrices. The statistic is based on a multivariate generalization of the Fisher r-to-z transformation. This statistic has small sample performance which is superior to an analogous likelihood ratio statistic obtained via the analysis of covariance…
