| Summary: | In multivariate statistical quality control, the existing tests known as Generalized Variance (GV) and Vector Variance (VV), plays an important role in measuring process variability.In this paper, we present the computational efficiency of both tests to illustrate that their complexity as a function of dimension. From the mathematical derivation
and simulation study, the computational efficiency of VV outperforms GV, particularly when the number of variables is
large. |
