Resumen de Directional Control Schemes for Multivariate Categorical Processes

Jian Li, Fugee Tsung, Changliang Zou

• The authors propose a simple Phase II log-linear directional control chart exploiting directional shift information and integrating multivariate categorical process monitoring into multivariate binomial and multinomial distributions. They propose a diagnostic scheme for identifying shift direction. The effectiveness of the control chart and the overall diagnostic approach are demonstrated through numerical simulations and real applications.
