The AEWMA Control Charts Based on Likelihood Ratio For Preliminary Analysis

摘要：

Two adaptive exponentially weighted moving average (AEWMA) control charts based on likelihood ratio statistics are proposed for preliminary analysis of individual observations.One focuses on detecting the shifts in location in the historical data and the other is more general can detect a shift in either the location or the scale or both.The simulated results show that the proposed two control charts are,respectively,superior to their competitors in the detection of sustained shifts and linear trend shifts.
