Cusum Chart

Cusum Chart - Web cusum charts identify small shifts (between.5 and 2 standard deviations) in your process means by charting a statistic that incorporates current and previous data values from the process. Given a sequence x1, x2, x3,., xn with estimated average mx and estimated standard deviation σx, define upper and lower cumulative process sums using: Because the cusum chart is cumulative, even minor drifting in the process mean will cause steadily increasing (or decreasing) cumulative deviation values.
