Setting up a DOE with a transformed Factor
Hi - I am setting up a simple 2 factor response surface design. We know from prior experimentation, that X2 is best used for model building in transformed units, which is in this case LN X2. The question is, would it be better to use for DESIGN GENERATION the LN X2, instead of going with the physical unit of X2? By using physical units and do a LN transform on X2 for analysis with the responses ob...
