5.3. Choosing an experimental design
5.3.3. How do you select an experimental design?
|Foldover designs increase resolution||Earlier we saw how fractional factorial designs resulted in an alias structure that confounded main effects with certain interactions. Often it is useful to know how to run a few additional treatment combinations to remove alias structures that might be masking significant effects or interactions.|
|Partial foldover designs break up specific alias patterns||
Two methods will be described for selecting these additional treatment
