Abstract
A numerical method is used to compute confidence intervals, which have exact coverage probabilities, for the mean of a normal distribution following a group sequential test. This method, which uses an ordering of the sample space similar to that employed by Siegmund (1978, Biometrika 65, 341-349), is contrasted with the usual confidence interval for the mean.
摘要
一种数值方法被用于计算置信区间，该置信区间对于正态分布均值在进行成组序贯检验后具有精确的覆盖概率。此方法使用的样本空间排序与西格蒙德（1978年，《生物统计学》65卷，341 - 349页）所采用的类似，它与均值的常规置信区间形成对比。
