Study on Likelihood-Ratio-Based Multivariate EWMA Control Chart Using Lasso

Purpose: When applying exponentially weighted moving average (EWMA) multivariate control charts to multivariate statistical process control, in many cases, only some elements of the controlled parameters change. In such situations, control charts applying Lasso are useful. This study proposes a nov...
