Plackett-Burman Design

Highly efficient screening design for many factors in multiples of 4 runs — only main effects identifiable.

Also known as: Plackett-Burman, PB design

Plackett-Burman designs (1946) are two-level screening plans whose run count is a multiple of 4 — e.g. 12, 20, 24, 28 runs. With runs one can screen up to factors. They shine when many factors (10–20) must be checked for significance with minimum effort.

  • Efficiency: factors in runs, where
  • Resolution IIImain effects are partially aliased with many two-factor interactions
  • Complex alias structure — each interaction is spread across many main effects rather than 1:1 as in classical 2ᴵᴵᴵ designs
