A new approximation method for obtaining a maximized multiple criterion, based on the formula of Edgerton and Kolbe ( 2 ), is presented. By applications to examples from the literature ( 1, 2 ), the new method is evaluated in comparison with the Horst approximation ( 1 ), a suggested revision of the Horst procedure, and the more exact but more laborious iterative method for the principal axis solution of Hotelling.
