SAS/QC 9.3 includes two new experimental procedures for multivariate process monitoring and enhancements to the CAPABILITY, FACTEX, and RELIABILITY procedures.
The new MVPMODEL and MVPMONITOR procedures are used together to monitor multivariate process variation over time in order to determine whether the process is stable or to detect changes in a stable process.
The MVPMODEL procedure provides computational and graphical tools for building a principal components model from multivariate process data in which the measured variables are continuous and correlated. This model then serves as input to the MVPMONITOR procedure.
The MVPMODEL procedure implements principal ...
