WebAug 12, 2024 · Example of a Half-Fraction Factorial Design (View the complete code for this example.) Note: See Half-Fraction Factorial Design in the SAS/QC Sample Library. Often you do not have the resources for a full factorial design. In this case, a fractional factorial design is a reasonable alternative, provided that the effects of interest can be ... WebFeb 1, 2024 · The defining relation for the complementary half-fraction is I = -ABC, or multiply both sides by C to equivalently obtain IC = C = -AB. This shows the complementary half fraction is in fact generated by C = -AB, while the original half-fraction was generated by C = AB. This is a general rule that applies to half-fractions. rac3216
