拉丁方是目前常用的一种实验设计方法,有一次性和重复性两种类型,其实验结果的统计学分析均采用方差分析法。鉴于拉丁方实验具有各因素(行间、列间、处理间、重复批间)划区内的例数相等的特点,可利用电子计算器将其方差分析方法简化。简化法的基本公式还适用于那些按因素划区时各区内例数相等的完全随机、区组随机、正交设计等实验资料的方差分析。一、基本公式设拉验丁方实验为k×k级,重复次数为m,则可
Latin square is a commonly used experimental design method. There are two kinds of one-time and repeatability. Statistical analysis of the experimental results adopts analysis of variance. In view of the fact that the Latin square experiment has the same number of cases in each area (between rows, columns, treatment rooms, and repeat batches), the variance analysis method can be simplified using an electronic calculator. The basic formula of the simplification method is also applicable to the analysis of variance of experimental data such as completely random, block random and orthogonal design with equal number of cases in each zone according to factors. First, the basic formula set up for the experiment Fang Ding experimental k k level, the number of repetitions is m, can be
