In the first part of this article , the problem of heteroscedasticity is put forward . the serious effect is also stated . in the first section of the second part , several commonly cited testing methods are introduced , such as graph method , spearman rank correlation coefficients test , park test , glejser test and goldfeld - quandt test
在第二节中，首先综述了各种文献中给出的常用的检验异方差的方法，它们有图示法、斯皮尔曼( spearman )的秩相关系数检验法、帕克( park )检验法、格莱舍尔( glejser )检验法、戈德菲尔德-匡特( goldfeld - quandt )检验法。
As goldfeld - quandt test can only be applied to one independent variable , it is generalized in the second section . it shows that , in multivariate situation , the data can be arranged according to their principle components . but there should be a premise : the disturbances of the lower data group should have equal variance and those of the higher data group have the same variance
由于戈德菲尔德-匡特检验方法只适用于一个自变量，因此，本文对g - q检验进行了推广，说明在多变量的情况下，可以利用主成分对样本数据进行排序，并强调使用戈德菲尔德-匡特检验的前提：低样本组各观察值的扰动项必须具有同方差性；高样本组各观察值的扰动项也必须具有同方差性，否则，检验的结果可能是错误的。
