✦ Synopsis

AbstractÐA control point methodology (CPM) is proposed for implementation of graphical cumulative-sum (CUSUM) control charts on computers. Currently, most computer implementation of CUSUM charts is based on tabular form which loses the distinguished look of CUSUM statistics and V-mask. The more intuitive graphical CUSUM charts are not popular due to the diculty of computer implementation. CPM removes the need to store all CUSUM points and thus reduces computing time. Examples are given to show that the proposed method can be applied to CUSUM for both means and ranges.

Gamma-camera uniformity is often monitored for quality control of performance. Many parameters can be derived from computer analysis of the image of a uniform (flood) source to obtain quantitative measures of uniformity. However, it is not clear which best reflect changes in uniformity, or how actio

In this paper simultaneous exponentially weighted moving average schemes for the mean and the variance of a financial time series are introduced. The target process is assumed to be a GARCH process. It is proved that in some cases the bivariate approach leads to a smaller out-of-control average run
