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 ...

An experiment studies the e ect of lighting conditions (factor A) and the speed of a rotating drum (factor B) on a subjects ability to focus on the center of the drum. In this experiment, it was easy ...
