Abstract and subjects
Design and analysis of factorial experiments with randomization restrictions has received considerable attention in recent years; motivated by studies of multi-stage processes or systems. This has given rise to seemingly unrelated methods of design construction, specific to the layout (e.g., split-plot, split-lot, strip-plot designs). We develop a general approach to this problem that includes most approaches in the literature as special cases, and is easily adaptable to designs which are combinations of different layouts.
