- Just a generalization to multiple predictors of the case of testing two
- univariate correlations for independent groups. Can be tested as a
- homogeneity of regressions in an analysis of covariance setup. In SPSS
- MANOVA:
-
- MANOVA DEPVAR BY GROUP(1,2) WITH COV1 . . . COVN
- /ANALYSIS=DEPVAR
- /DESIGN=GROUP, POOL(COV1 . . . COVN), GROUP BY POOL(COV1 . . . COVN)
