Furthermore, analysis tools for\nFractional Factorial designs with 2-level factors are offered\n(main effects and interaction plots for all factors\nsimultaneously, cube plot for looking at the simultaneous\neffects of three factors, full or half normal plot, alias\nstructure in a more readable format than with the built-in\nfunction alias).",
