SUMMARY. The concepts of D-, E- and A-optimality are extended to consider designs for estimating the slopes of a response surface. Optimal designs under the D-optimality criterion are obtained for second-order models over spherical regions.
AMS (1991) subject classification. 62K99, 62K05.
Key words and phrases. Minimax designs, optimal designs, second-order designs, spherical regions.
