A note on the lower bounds on maximum number of clear two-factor interactions for $$(2^{m - p}_{III})$$ and $$(2^{m - p}_{IV})$$ designs. (English) Zbl 1093.62073
Summary: The clear effects criterion is one of the most important rules for selecting $$2^{m - p}$$ designs, and it is valuable to know the maximum number of clear two-factor interactions in $$2^{m - p}$$ designs. This article provides lower bounds on the maximum number of clear two-factor interactions for $$2^{m-p}_{III}$$ and $$2^{m-p}_{IV}$$ designs by constructing specific designs, respectively. The lower bounds improve the ones given by B. Tang et al. [Can. J. Stat. 30, No. 1, 127–136 (2002; Zbl 0999.62059)] and the construction methods perform quite well.
