Regular Designs may not Always be the Best Choice for Screening • In regular designs the alias matrix consists of either 0, +1 or -1 entries • That means that effects are completely confounded • Unless the experimenter has some “process knowledge”, effects cannot be separated without conducting additional experiments – Fold-over – Partial fold-over – Optimal augmentation 34
