摘要
正交平衡区组设计(或广义正交表)的数据分析类似于正交拉丁方(或正交表)的数据分析.利用类似于正交表数据分析中的投影矩阵的正交分解技术,研究正交平衡区组设计的统计分析模型,给出了方差分析中的二次型以及各因子的二次型的分布性质,从而给出正交平衡区组设计统计模型中的方差分析方法.
Data analysis of orthogonal balanced block designs (or generalized orthogonal arrays) can be done similar to that of the orthogonal Latin squares (or orthogonal arrays) since the orthogonality of orthogonal balanced block designs (or generalized orthogonal arrays) is equivalent to that of projection matrices (or their matrix images). By using the orthogonal decomposition of projection matrices, the sum of square of the factors, the distributions of all quadratic form statistics in a statistical model of orthogonal balanced block designs, are discussed, the method of analysis of variance is given.
