Split-Plot Experiments with Unusual Numbers of Subplot Runs

Summary: [This abstract is based on the author's abstract.] When experiments cannot be run in a completely randomized fashion, certain split-plot experiments may be used. Most split-plot designs described in the literature are based on 2-level factorials where the number of subplots is a power of 2. However, some situations require an unusual number of subplots. This issue is explored and some examples based on Plackett and Burman designs are provided and compared to algorithmically constructed D-optimal split-plot designs.
