Abstract
An extension of the Dunnett test for comparing k experi-mental groups with a single control group is presented for the multivariate case when the control group may contain as many as seven times the cases contained in each experimental group. test, based on coorrelated Hotelling T 2 statistics, uses a simple adjustment to the equal-n critical values to arrive at values which are slightly conservative over a wide range of unbalanced designs. A real-world application is presented.
