The properties of D-optimal designs for multiresponse models are explo
red using the Equivalence Theorem by Fedorov [''Theory of Optimal Expe
riments,'' Academic Press, New York, 1972]. For some classes of multir
esponse linear models, the results can be applied to simplify complica
ted multiresponse experimental design problems or to reduce multirespo
nse experimental design problems to single-response experimental desig
n problems using the D-optimal design criterion. (C) 1994 Academic Pre
