Blocked DSD results in quadratic effect confounding
I created a 20 run blocked 7-factor DSD with 5 continuous & 2 categorical effects. There are five blocks with 4 randomized runs/block; as advised by JMP experst in each block there are center runs, in this case two/bock; I get a DSD where confounding of the quadratic effects is acceptable. However by adding dummy factors in order to increase runs and factor estimation power I get blocked DSD's wit...
