Abstract

We compare the performance of two phase II monitoring schemes for linear profiles, one based on the classical calibration method monitoring the deviations from the regression line (referred to as the NIST method) and the second based on individually monitoring the parameters of the linear profile (referred to as the KMW method). The comparison criterion is average run length performance under different sustained shifts in the intercept, slope and error standard deviation of the linear calibration line. A simulation study shows that the NIST method performs poorly compared to the combined control charting scheme of the KMW method.
