Largest possible model for a DSD?
I was watching the following Youtube video below where Dr. Ramsey is showing how to analyze a 6-factor DSD with 4 center points (total runs = 17). At around the 5:25 mark he's showing how to use best subsets/all possible models to reduce the full quadratic model, and mentions the maximum number of terms for this DOE has 9 terms. He says to calculate this number, take the number of unique settin...
