Extensions Of Multivariate Coefficient Of Variation Control Charts
Control charts for monitoring multivariate coefficient of variation (MCV) are applied when the interest is in monitoring the relative multivariate variability to the mean vector of a multivariate process. This thesis proposes an upper-sided variable sampling interval (VSI) exponentially weighted mov...

| Summary: | Control charts for monitoring multivariate coefficient of variation (MCV) are applied when the interest is in monitoring the relative multivariate variability to the mean vector of a multivariate process. This thesis proposes an upper-sided variable sampling interval (VSI) exponentially weighted moving average (EWMA) chart to detect upward shifts in the MCV squared ( |
