Abstract:
|
A construction method, based on nonregular fractions, is presented for small two-level designs which are performed in more than one stage andwhich have a split-plot structure in each stage. These designs are called "non-regular split-lot designs". The construction method yields designs with a small number of aliased factorial effects and a small number of factorial effects that are confounded to whole plot contrasts. A key concept is that of "relatively independent subspaces",which allows construction of (ideally disjoint) subspaces whose elements are associated with the factorial effects in the different stages of a design.
