Mixture DOE with covariate batch effects
I have to generate a DOE with 7 mixture effects and 6 continuous covariate factors. The covariate factors are measurements of raw material batches, only 20 bathes are available. Mixture and quadratic covariariate effects as well as mixture -covariate interactions need to be estimate using a Kowalski with only 2nd order interactions. The number of runs exceeds #batches so repeated sampling from eac...
