摘要
It was recently demonstrated that homogeneously weighted moving average (HWMA) control charts are improper devices for an online detection of changes within a series of random variables. However, another attempt was made to bail out the concept underlying these charts. Here we want to re-emphasize that HWMA charts are dispensable by rebutting the arguments of the latter contribution.
