Abstract:
New three-level designs for fitting second-order response surfaces are obtained by three methods. New designs for 9, 10, and 13 factors are obtained by combining two-level factorial designs and incomplete block designs. New designs for 6, 8 and 10 factors are obtained by design rotation these designs are rotations of central composite designs. Two sequences of design for 7, 11 and 15 factors are obtained by using a Hadamard matrix to reduce v1 linearly dependent variables to a design for v factors. One of these sequences of design corresponds to a rotation of uniform shell designs the other sequence is complementary to the rotated uniform shell designs in the sense that the Os and or - 1s of the design points are interchanged.
