A simple test for normality against asymmetric alternatives
针对非对称备择的简单正态性检验
The mean and the variance of a random sample are independently distributed if and only if the parent population is normal. This characterization is used as a basis for developing a test, termed the Z test, for the composite hypothesis of normality against asymmetric alternatives. The null distribution of the Z test statistic is for practical purposes satisfactorily approximated by a normal distribution for samples of size 5 up to 100. The large sample null distribution and…
