Resumen de Optimal Foldover Plans for Two-Level Fractional Factorial Split-Plot Designs

Robert G. McLeod, John F. Brewster

• The foldover technique is useful as a follow-up strategy when the objective is to de-alias effects of interest after the initial fractional factorial split-plot design has been run. The resulting combined design is a blocked fractional factorial split-plot design. Using the minimal aberration criterion for blocked fractional factorial split-plot designs, a catalog of optimal foldover plans is provided for initial minimal aberration fractional factorial split-plot designs of 16 and 32 runs.
