一、排满正交表的情况某试验考察 A、B、C、D、E、F、G 七个因素,各取二水平,不考虑因素之间的交互作用,用正交表 L_8(2~7)安排。这就组成了一个无重复、无空列、不考虑交互作用的七因素二水平正交试验。现将其结果分析方法介绍如下(参看表1)。第一步:收集数据。为了计算方便,可将每个试验指标值分别减去一个接近于总平均数的常数,将指 First, the situation filled with orthogonal table A test study A, B, C, D, E, F, G seven factors, each taking two levels, without considering the interaction between factors, using orthogonal table L_8 (2 ~ 7) arrangements. This constitutes a non-repetitive, no empty list, do not consider the interaction of seven factors and two orthogonal test. Now the result analysis method is as follows (see Table 1). The first step: collect data. For convenience of calculation, each test index value can be subtracted by a constant close to the total average,
