正态样本中上（下）异常值的检验

Testing for Many Upper (Lower) Outliers in Normal Samples

关于正态样本下多个异常值的检验，各种文献中仅对异常值个数已知的情况作了讨论．当异常值个数未知时，本文成功的找到了确定异常值个数的方法．此法简单有效。

For the test of many outliers in normal samples,most literature only dealt with the case in which the number of outliers is known. When the k is unknown,in the paper,we successfully find a way of determing k,which can completely eliminate masking and swamping effect.
