Effects of Using Generalized Moving Averages of Stationary Process Data and Their Applications

Abstract
Due to the high frequency sampling of on-line data acquisition systems, most of the on-line data are auto correlated. The autocorrelation of the process data has impacts on the applications of statistical analysis methodologies since the assumption of uncorrelated observations will not be valid. The effect of the autocorrelation can be reduced by some data treatment mechanism such as using large sampling intervals. However, this approach discards the intermediate data and thus increases the possibility of missing important events in the process. In this article, the effects of using generalized moving averages can be calculated. The applications of these results can be found in process control in various industries.Citation
