Monitoring process mean and variability with generally weighted moving average control charts
TL;DR: It is shown that the combination of the generally weighted moving average (GWMA) mean chart and a two-side GWMA variance chart is more sensitive than the combined EWMA charts for detecting small shifts in the process mean and variance.
