Peer reviewedNordlund, Daniel J.; Nagel, Rollin – Journal of Educational Statistics, 1991
Reasons/methods for standardizing discriminant function coefficients are reviewed, and use of the pooled within-groups variance estimate is examined. Use of total or pooled within-groups estimates can be justified only on purely mathematical grounds. Total variance estimates offer a more consistent and parsimonious approach than do pooled…
