截尾序贯验后加权检验截尾点的优化设计

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。本文用优化技术确定截尾点Ｃ，克服了实践中确定停时Ｎ和截尾点Ｃ遇到的计算困难，避免了一般取Ｃ＝１的盲目性，使截尾点Ｃ的选取有了理论根据。优选的截尾点不仅使双方承担的风险之和最小，而且使双方承担的风险值相对合理，易于接受。

Optimal Design of Truncating Point in Truncated Sequential Posterior Odd Test

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. In the paper, the authors apply the optimization techniques to determine the truncating point. Having avoided selecting C=1, this method can overcome the difficulties in selecting the stop time N and truncating point C, and malle the selection of C more theoretically. The optimal truncating point minimizes the risks undertaken by both sides become and makes them more acceptable.
