Gower distance-based multivariate control charts for a mixture of continuous and categorical variables

作者:

Highlights:

• We propose new nonparametric multivariate process monitoring techniques.

• Proposed control charts can efficiently handle mixed data.

• Integration of Gower’s dissimilarity coefficient and Hotelling’s T2 control charts.

• We examine the performance under various simulation and real scenarios.

• Performance of the method improves as the number of categorical variable increases.
