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, ...

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 ...

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.

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 ...
