Commentary on Biasing Effects of Pilot Samples and Gillett's Observations on the Stein Confidence Interval
评论了使用试点样本确定样本量时存在的可纠正偏差，并反驳了Gillett认为Stein方法更优的观点，指出其追求人为目标、不切实际且存在未达标效应。
A previous note demonstrated that correctable bias is present when pilot sample information is used to establish sample size. Though Gillett claims that the Stein approach is a superior method for establishing sample size, we argue that it pursues an artificial goal, is impractical, and is subject to the underachievement effect that prompted our original note.
