Greenhouse-Geisser校正公式是一种用于修正F统计量的方法,常用于分析因素设计的方差分析。在SPSS等统计学软件中,此方法被广泛使用,主要用于对违反球形假设的数据进行校正。 当数据不满足球面性时,即存在违反球形假设的情况,我们就需要对F统计量的自由度进行修正。此时,最常用的修正方法就是Greenhouse-Geisser校正。同时,...
Greenhouse-Geisser 校正 违反了球形检验后,可以使用该校正. 校正得到的epsilon 假设因素水平个数为k=3,每个水平下有n=10个数 则因素自由度a1=epsilon(k-1) 误差自由度a2=epsilon(k-1)(n-1) F(a1,a2)
