Abstract

See full text

Variables associated with a multivariate process are monitored on a periodic basis. As a result of an observation of the variables, a residual standard deviation between the monitored variable values and a predictive model can be determined. The residual standard deviation is plotted as a series of connected points. Through the use of an adaptive model, the observations of the variables, and in turn, the residual standard deviation and the predictive model are adapted to changes in the multivariate process.
