MATHEMATICAL MODEL OF THE L_n (s_1×s_2×…×s_k)DESIGN AND ITS THE STATISTICAL ANALYSIS

给出Ｌｎ（Ｓ１×Ｓ２×…×Ｓｋ）正交设计的数学模型，并在线性模型一般理论的基础上，对正交设计模型中的估计问题进行了统计分析．

This paper gives the mathematical model of the Ln (s1×s2×…×sk) design,and on the basis of the theory of the linear model,makes the statistical analysis for the estimate question of the Ln(s1×s2×…×sk)design model.
