A Multivariate Test of Homogeneity of Regression Weights for Correlated Data.
Peer reviewed Peer reviewed
James, Lawrence R.; Tetrick, Lois E. – Educational and Psychological Measurement, 1984
An analytic procedure is presented for testing the homogeneity of unstandardized regression weight vectors when the vectors are correlated. The basic design involves repeated measurements on a dependent variable and a set of independent variables. The method is illustrated with a study of perceived leader behavior. (Author/BW)

A Multivariate Test for Sequential Moderation.
Peer reviewed Peer reviewed
James, Lawrence R.; And Others – Educational and Psychological Measurement, 1982
An analytic procedure is presented which casts sequential moderator analysis in the role of a multivariate test of parallelism of regressions. The procedure addresses a test for comparing predictor-criterion relationships for one set of measurements or multiple predictors and repeated measurements on a criterion. (Author/PN)
