In many experimental situations, when a two-level factorial design is performed, the effects of higher order interactions are usually less important than the effects of lower order interactions (and effects of the same order are equally important). Hence, we should search for good fractional factorial designs withN observations allowing for the estimation of the effects of main factors and of some interactions under study. Obviously, a design is more preferable it if allows for several de… CONTINUE READING
