oa Journal of Applied Science in Southern Africa - Further developments in the construction of multivariate control charts

  • ISSN : 1019-7788



This paper presents an alternative method of constructing Multivariate control charts. The method is based on a statistic referred to hereafter as the Studentised Hotellings statistic. From simulated data and industrial data, this method seems to be better than the usual methods in that it clearly shows the out-of-control observations. That is, it seems to have more power than the procedures currently in use. In addition it extends the work of Nola D. Tracey et al. (1992) on individual observations, to the more practical situation where subgroups are used.
