Double factorial - Wikipedia
WebIn general, we pick a fraction such as ½, ¼, etc. of the runs called for by the full factorial. We use various strategies that ensure an appropriate choice of runs. The following sections will show you how to choose an appropriate fraction of a full factorial design to suit your purpose at hand. 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
