对比矩阵描述实验问题

描述----------Description----------
This matrix of numerical constants describes the experimental question, say p. Each experimental question is described by a single contrast vector (a single row in cmat) or by a contrast matrix (several rows in cmat). The ordering of the columns corresponds to that of the associated design matrix X. Thus, typically the first two elements in a row of cmat are reserved for for the two dyes. E.g. the first line of the matrix cmatB.AB describes the main effect B.
这个数字常量的矩阵描述了实验的问题,说。每个实验的问题是由一个单一的反差对比矩阵(CMAT几行)向量(CMAT中的单列)或描述。列的顺序对应,因此,通常是首两在CMAT行的元素为两种染料保留相关的设计矩阵X。例如的的矩阵cmatB.AB的第一线,介绍了主要作用B.
