Minimum aberration designs with two-level and four-level factors. (English) Zbl 0769.62058
Summary: For optimal assignment of factors to columns of a $$4^ m 2^ n$$ design, we consider extensions of the minimum aberration criterion for the 2- level designs. Minimum aberration $$4^ 1 2^ n$$ and $$4^ 2 2^ n$$ designs in 16 and 32 runs are obtained and tabulated. Some results on the wordlength patterns and design classification are obtained.
