WebThe CUSUM Chart CUSUM (Cumulative Sum) charts improve the ability to detect small shifts (i.e. less than 1.5 σ) by charting a statistic that incorporates current and previous data values from the process. Specifically, the CUSUM chart plots the cumulative sums of the deviations of the sample values from a target value. WebCusum charts display how the group summary statistics deviate above or below the process center or target value, relative to the standard errors of the summary statistics. Useful to detect small and permanent variation on the mean of the process. Value. Returns an object of class 'cusum.qcc'. mobility bites side effects
