| 摘 要： | MEWMA控制图是最有应用价值的多元控制图之一.然而,当MEWMA图发出失控信号时,很难说明哪个变量或哪些变量处于失控状态.笔者利用主成分分析进行MEWMA控制图失控信号的诊断,并引用Lowry等人提出的实例进行了实证分析.

| Abstract: | MEWMA control chart is one of the most applied multivariate control charts. However, when a MEWMA chart issues a signal, it is difficult to identify which variable or set of variables is out of control. This article applies principal component analysis to diagnose signals in MEWMA charts and gives a demonstration combined with the example brought forward by Lowry. |
