Efficiency of confidence intervals generated by repeated subsample calculations
重复子样本计算所生成置信区间的效率
Confidence intervals for a mean may be obtained from n observations continuously and symmetrically distributed about the mean, by computing the means of all 2n − 1 subsets, or subsamples, of the observations. The true mean lies in each of the intervals between the ordered subsample means with probability 2−n. In order to reduce the 2n − 1 computations of means, a random subset of subsample means may be used, or a ‘ balanced’ subset may be selected satisfying certain group…
