The cumulative sum (CUSUM) chart is designed to better detect small, sustained changes in the process mean than an X-chart.
The important thing with CUSUM charts is not the absolute value of the CUSUM; it is the slope of the curve and any changes in this slope:
CUSUM analysis flagged a county-wide increase in macrolide antibiotics on the day of treatment/prophylaxis for the first case and contacts in the outbreak.
All 3 methods are based on a positive 1-sided CUSUM calculation.
Quintos's rank test is very different from the traditional CUSUM and Chow tests for parameter stability, because her rank test checks for stability of the cointegrating relationship between variables.
To detect small shifts in the process, two other charts have been invented: the EMWA chart (Montgomery[2]) and the CUSUM chart (Barnard[3], Schein and House[4]).
The predicted residuals from this model are then analyzed by using the cumulative sums method (PROC CUSUM) (18,19).
The resistance value (for binary tests 0 = susceptible or 1 = nonsusceptible; for quantitative tests, the actual MIC) for each isolate was then passed to CUSUM (binary only) or MA (binary and quantitative) modules, where alerts were generated on the basis of control limits.
