Definitive screening designs - correlated vs. confounded second-order effects
One line I've seen mentioned regarding DSDs is that for any 6-factor experiment, the full response surface can be fitted within 3 factors. However, one of the tradeoffs of DSDs is that two-factor interactions are correlated with other two-factor interactions and quadratic terms, despite none of them being confounded. If I'm understanding this correctly, this at least allows us to estimate the two-...
