Linear Versus Quadratic Multivariate Classification
Peer reviewed Peer reviewed
Huberty, Carl J.; Curry, Allen R. – Multivariate Behavioral Research, 1978
Classification is a procedure through which individuals are classified as being members of a particular group based on a variety of independent variables. Two methods of makin such classifications are discussed; the quadratic method is seen to be superior to the linear under certain constraints. (JKS)

An Approximate Test for Comparative Discriminatory Power
Peer reviewed Peer reviewed
Goldstein, Matthew – Multivariate Behavioral Research, 1976
Suppose P to the subpower of 1 and P to the subpower of 2 are two competing discrimination procedures. To compare the relative discriminatory power of both procedures, test statistics are suggested for the hypothesis that P to the subpower of 1 and P to the subpower of 2 performed no better than random assignment versus the alternative that P to…

The Use of Analysis of Covariance Structures for Comparing the Psychometric Properties of Multiple Variables across Populations.
Peer reviewed Peer reviewed
Rock, Donald A.; And Others – Multivariate Behavioral Research, 1978
Systematic procedures are outlined for testing the assumption made on the dependent variables in a variety of statistical techniques. Specifically, procedures are outlined for testing the assumption that the dependent variables are measuring the same constructs in the same metrics with equivalent reliabilities across all subgroups.

A Review of STATGRAPHICS.
Peer reviewed Peer reviewed
Cohen, Jacob; Lee, Robert S. – Multivariate Behavioral Research, 1987
STATGRAPHICS, a statistical package written for the IBM PC/XT/AT, is reviewed. In addition to superb graphics, STATGRAPHICS is unequalled in time series procedures, quality control, linear programming, and other mathematical procedures. The modules for regression analysis, categorical data analysis, and nonparametric analysis are good, but contain…
