Multivariate Control Charts For Attribute Data, Donald S. Holmes, A. Erhan Mergen

Presentations and other scholarship

In this paper the use of multivariate control charts for attribute data is proposed. These charts are based on chi-square statistics. Data from various categories can be summarized into a multivariate statistic, i.e., the chi-square statistic, and then the process can be monitored by plotting this statistic on a control chart. A numerical example is provided.
