Block designs for incomplete factorial treatment structures with two factors

Not AvailableIn this paper, the problem of obtaining efficient block designs for incomplete factorial treatment structure with two factors excluding one treatment combination for estimation of dual versus single treatment contrasts is considered. The designs have been obtained using the A-optimal completely randomized designs and modified strongest treatment interchange algorithm. A catalog of efficient block designs has been prepared for m1 = 3, 4 and m2 = 2, b<=10 and k<= 9 and for m1 = 3,4 and m2 = 3, 4, b<=≤ 10 and k <= 10.Not Availabl
