The book "Split-Plot Designs" by Ashraf Almimi offers a comprehensive analysis and extension of methods for conducting split-plot experiments, which are often used in industry due to time and cost constraints as well as limitations in the randomization of treatment combinations. It addresses the challenges that may arise when analyzing results from fractional factorial split-plot experiments and provides solutions for separating effects of interest. The work includes the development of rules for creating foldovers for designs with minimal aberration, as well as methods for estimating missing observations in unreplicated two-stage factorial and fractional split-plot designs. Additionally, numerical and graphical methods for verifying the assumptions and fit of split-plot models are presented.
