Definition

A minimum aberration design is one that achieves the greatest resolution and minimizes the aliasing of Main Effects and two-factor Interactions in its class of designs. Note: minimum aberration designs are not necessarily minimum run designs, i.e., they may not be the smallest designs to achieve the goal of maximum resolution.
