Supplementary sample nonparametric empirical Bayes in a quality control situation
质量控制中的补充样本非参数经验贝叶斯方法
The supplementary sample nonparametric empirical Bayes procedure (Krutchkoff, 1967) is slightly modified here and compared with the classical quality control procedure by Monte Carlo simulation. It is found that the empirical Bayes procedure is generally more powerful and will usually detect an out-of-control situation sooner than the classical procedure.
