Simultaneous Univariate X_bar Charts to Control Bivariate Processes with Autocorrelated Data

In this article, we consider the simultaneous univariate X_bar charts (SU X_bar charts) for samples of n bivariate observation vectors that are not only cross‐correlated but also autocorrelated. The cross‐covariance matrix of the sample mean vectors was derived with the assumption that the observati...
