Permuting regular fractional factorial designs for screening quantitative factors
通过水平置换改进定量因子筛选的正规部分因子设计
Fractional factorial designs are widely used in screening experiments. They are often chosen by the minimum aberration criterion, which regards factor levels as symbols. For designs with quan-titative factors, however, permuting the levels for one or more factors could alter their geometrical structures and statistical properties.We provide a justification of theminimum β-aberration crite-rion for quantitative factors and study level permutations for regular fractional…
