Hi, I have a mixture design with 6 factors. I'm interested in first and second order interactions for which I'll have a minimum of 22 runs. Is there anyway to add/augment the 6 factor mixture design to add or substitute more factors such that I build/use the data from the 6 factor design?
You could manually add a new column to the existing data table for the new factor. Add the Mixture, Design Role, and Changes column properties or whatever properties are required for the type of the new factor. Enter the levels for the new factor for the existing runs. Then follow DOE > Augment Design. Here you can adjust the factor ranges and the terms in the model.
