Abstract:
:The advantages of performing simultaneous inferences on the means of several response variables using multivariate analysis of variance are discussed. They include control over the problem of declaring false significant differences and the ability to investigate the effects of treatment on a given response variable after eliminating variations due to other response variables. Computational equivalencies with multiple linear regression in the two-group case are also discussed.
