Abstract
Biochemical quality control data have been reported to be autocorrelated. Serial correlation may increase the rate of false alarms and decrease that of true alarms if traditional control charts are used. In this paper, the times series were examined and the performance of the EWMAST chart was compared to that of the EWMA chart in the presence of correlation.Citation
