We proposed a new method of truncating estimation when the means are known, which can weaken the influence of outliers.

在均值已知的情况下，提出变点的截尾估计方法，以消除厚尾随机变量序列中较多“奇异”点对估计结果的影响；

It is very important to select a truncating point in the truncated sequential posterior odd test (SPOT), but there is no efficient method to solve the problem up to now.

选取截尾点是截尾序贯验后加权检验很关键的一步，目前理论上尚无有效的选取方法。
