It is increasingly recognized that many industrial and engineering experiments use split-plot or other multistratum structures. Much recent work has concentrated on finding optimum, or near-optimum, ...

In this section we are interested in recognizing and understanding three other types of experimental designs. These are designs with subsampling, split plot designs, and repeated measures designs.

The treatment-design portion of fractionated two-level split-plot designs is associated with a subset of the 2 n-k fractional factorial designs. The concept of aberration is then extended to these ...

PROC MIXED can fit a variety of mixed models. One of the most common mixed models is the split-plot design. The split-plot design involves two experimental factors, A and B. Levels of A are randomly ...
