WebA foldover design is obtained from a fractional factorial design by reversing the signs of all the columns: A mirror-image fold-over (or foldover, without the hyphen) design is used to augment fractional factorial designs to increase the resolution of \( 2_{III}^{3-1} \) and Plackett-Burman designs. It is obtained by reversing the signs of all the columns of the …
