| 摘 要： | 讨论了两种多元累积和图.第1种是利用 Hotelling 统计量进行累积和,形成多元累积和控制图,并讨论了它的平均游程长度(ARL);第2种是在已知偏移状态下,用序贯概率比检验法将多元累积和问题转化为一元累积和问题.这两种方法的前提都是随机变量服从正态分布. |
| 关 键 词： | 控制图 累积和 平均游程长度 序贯概率比检验 |

| Abstract: | This paper presents two methods for designing multivariate CUSUM quality control procedures.The first is to form a multivariate CUSUM through replacing the statistic of a univariate CUSUM by the statistic of multivariate CUSUM.The second,which is related to sequential probability ratio test,reduces multivariate CUSUM to a univariate nomral CUSUM when the mean in the bad state(or at least the bad direction)is known. |
| Keywords: | control chart cumulative sum average run length sequential probability ratio test |
