A New Robust Multivariate EWMA Dispersion Control Chart for Individual Observations
A multivariate control chart is proposed to detect changes in the process dispersion of multiple correlated quality characteristics. We focus on individual observations, where we monitor the data vector-by-vector rather than in (rational) subgroups. The proposed control chart is developed by applyin...
