A Change-Point Based Control Chart for Detecting Sparse Changes in High-Dimensional Heteroscedastic Data
Zezhong Wang, Inez Maria Zwetsloot
Because of the curse-of-dimensionality, high-dimensional processes present challenges to traditional multivariate statistical process monitoring (SPM) techniques. In addition, the…
A Review of Dispersion Control Charts for Multivariate Individual Observations
Jimoh Olawale Ajadi, Zezhong Wang, Inez Maria Zwetsloot
A multivariate control chart is designed to monitor process parameters of multiple correlated quality characteristics. Often data on multivariate processes are collected as individ…
Should Observations be Grouped for Effective Monitoring of Multivariate Process Variability?
Jimoh Olawale Ajadi, Inez Maria Zwetsloot
A multivariate dispersion control chart monitors changes in the process variability of multiple correlated quality characteristics. In this article, we investigate and compare the…
