Group-wise monitoring of multivariate data with missing values
K Seo, J Lim, Y Kim - Journal of Quality Technology, 2024 - Taylor & Francis
In this article, we aim to detect the changes in the process that generates multivariate data
by monitoring their mean shift. To do this, we utilize a graphical tool known as a multivariate …
