Scheffe Cubic Mixture and p-value
I designed a Scheffe cubic DOE and completed the experiment. When building the model with the data set, I evaluated the p-values. However, some of my colleagues told me that p-values are meaningless for mixture designs. It does not make too much sense to me since not all mixtures have to have none linear factors, and therefore they don't need to be in the model.I am hoping to get more input from t...
