摘要：The proliferations of the various means through which data can be accessed technologically via computershave led to a huge enthusiasm in the simultaneous monitoring of several correlated quality characteristics. Hotelling’s2 T is a famous statistic that is so significant in identifying a shift that is due to the mean vector of a multivariatenormal distribution. When there is signals in a multivariate control chart, it is a clear indication that special causevariation exist in the process, as such effort must be made to identified which variable (s) is/are responsible for the outof control condition. In this study, we have demonstrated the use of mason, Young and Tracy (MYT) approach inidentifying non-random quality characteristics.
