I've found my optimum categorical level; how do I drop the rest during design augmentation?
Let's say I've designed my initial main effect screening experiment, where one of the factors is a 3-level categorical (A, B, C). After the first set of experiments, I'm fairly certain that level B is my process optimum decision and want to augment the design to get two-factor interactions, etc. How do I restrict the design augmentation to only explore the B level?
