[This abstract is based on the authors' abstract.]A proposed visualization tool consisting of a two-sided CUSUM and star glyphs is capable of determining when and which variables contribute to out-of-control signals. Combined with traditional multivariate control charts, the proposed method provides additional diagnostic information and can handle responses with high dimensions. Simulation results provide a guideline for implementing the methodology.
