Abstract:
|
This study analyzes stepwise discriminant analysis as a follow-up to a significant Hotelling's T2 control chart using squared partial correlations. Different levels of monitored variables, effect sizes, correlations, sample sizes, and alpha levels are considered. Due to its multivariate nature, it is hypothesized that the results of this study may demonstrate that stepwise discriminant analysis using squared partial correlations is an effective and accurate follow-up procedure for statistical process control (SPC). In addition, the results of this study may result in recommendations surrounding number of monitored variables, effect sizes, correlations, sample sizes, and alpha levels for practitioners using stepwise discriminant analysis as a post hoc procedure to a significant Hotelling's T2 in practice.
