Recent Advances in Process Monitoring: Nonparametric and Variable-Selection Methods for Phase I and Phase II

Summary: [This abstract is based on the authors' abstract.] The main aim of this article is to review and discuss two particular topics of statistical process monitoring: the need for a nonparametric approach to Phase I analysis and the use of variable selection–based control charts in multivariate Phase II monitoring. After discussing a number of critical issues related to these topics, the author presents recently proposed solutions and summarizes several research problems that require further investigation.
