DOI: 10.5705/ss.202018.0041
Abstract: The conditional main effect (CME) parameterization system resolves the long-standing aliasing dilemma of the traditional orthogonal components system for two-level regular fractional factorial designs. However, the algebra of the CME system is not yet fully… read more here.
