Hess, Brian; Olejnik, Stephen; Huberty, Carl J.
Educational and Psychological Measurement, v61 n6 p909-36 Dec 2001
Studied the efficacy of two improvement-over-chance or "I" effect sizes derived from predictive discriminant analysis and logistic regression analysis for two-group univariate mean comparisons through simulation.
