整区因子更重要时一般最小低阶混杂裂区设计

General minimum lower-order confounding split-plot designs when the whole plot factors are more important

考虑当整区因子比子区因子更重要时一般水平的裂区设计,提出了这种情况下的一般最小低阶混杂准则.用有限投影几何作为工具,建立了裂区设计与其补设计字长型之间的关系.这对构造该准则下的最优设计是有帮助的.

The general level split-plot designs when the whole plot factors are more important than the subplot factors are considered in the paper.The criterion of general minimum lower-order confounding in this case is proposed.By usingthe finite projection geometry as a tool,the relationship between the split-plot designs and its complementary sets is established,which is helpful to construct the optimal designs under this criterion.
