格拉布斯准则 C#实现　 剔除异常值
格拉布斯准则
格拉布斯准则是以正态分布为前提的，理论上较严谨，使用也方便。
某个测量值的残余误差的绝对值 |Vi |>Gg，则判断此值中有较大误差，应以剔除，此即格拉布斯准则。(Grab J function C#
grubbs criterion
The Grab J criterion is based on the normal distribution, and it is more rigorous in theory and convenient in use.
The absolute value of the residual error of a measured value is |Vi |>Gg, and there is a large error in this value, which should be eliminated, that is, GRA Bruce criterion.)
