• Resumen

  • An important property of any experimental design is its power, defined roughly as its ability to detect active factors. For supersaturated designs, power is even more critical. This article considers several popular supersaturated design construction criteria in the literature. The authors propose several of their own, and perform a simulation study to evaluate them in terms of power. Two analysis methods are used: forward selection and the Dantzig selector. The authors find that although the Dantzig selector clearly outperforms forward selection, there is no clear winner among the design construction criteria.
