Objective We describe the adaptation of the decision limit cumulative sum method ( CUSUM ) to internal quality control in clinical laboratory. 目的本文描述了改编的决定限累积和(CUSUM)方法应用于临床检验质量控制。
We studies the mean change point in the process with ARCH innovation by CUSUM ( Cumulative sum ) statistic. 利用累积和(CUSUM)(CUSUM)统计量对新息为ARCH过程的均值变点进行估计。
Based on the cumulative operator and its algorithm, fundamental principle of Cumulative sum Method is presented. 基于累积算子及其算法,论述了累积法的基本原理;
Combined with the Tabular Cumulative Sum Control Chart, it can be used to the environment of small batch production. 该图可以与表格式累积和(CUSUM)控制图联合应用于小批量生产条件下的质量控制,文章还用实例验证了该方法的有效性和可行性。
Second, by using cumulative sum methods of the traditional process and time series model, this paper builds the CUSUM control charts for monitoring the auto-correlated process, and provides the implementation methods of CUSUM control chart for monitoring the autocorrelation process. 其次,通过常规过程的累积和(CUSUM)构造方法和时间序列模型,构建了自相关过程的累积和(CUSUM)控制图,并提供了实施方法。
