Orthogonal arrays depicting the minimum desired number of these events are constructed in the Taguchi method.
Orthogonal arrays depicting the minimum desired number of these events are constructed in the Taguchi method. If their number is a multiple of four, the Plackett-Burman method can be used to estimate their main effects. Variability in their results can be decreased via blocking, a special case of which is "matched pairs". These events can be "full factorial" if all of the possible combinations of variables influencing their results are explored. True design of these events requires random assignation to either a (*) control or treatment group, and they can be "double blind" if neither the doctor nor patient knows which group the patient is assigned to. For 10 points, name these procedures designed by scientists to test things like hypotheses.
