Average Efficiency Factors and Adjusted Orthogonality in Multidimensional Designs
给出了连通多维设计平均效率因子的上界，并证明当设计具有调整正交性时，其平均效率因子是各分量设计平均效率因子的简单函数。
SUMMARY An upper bound is given for the average efficiency factor of a connected multidimensional design. It is shown that, when the design has adjusted orthogonality, its average efficiency factor is a simple function of the average efficiency factors of its component designs.
