摘要
当精度和可靠度给定时，Stein（1945）提出了两阶段抽样方法，构造了同时满足一定可靠度与精度的区间估计．本文则利用数值计算方法，进一步给出了此两阶段抽样中最优的第一阶段抽样量．
When precision and confidence are given, Stein (1954) proposed a two stage smple method, and constructed a confidence interval.This paper use numerical experiment and evaluation to give the first stage optimal sample quantities
