If you are using the CUSUM procedure for the first time, begin by reading PROC CUSUM Statement to learn about input data sets. Then turn to Getting Started: XCHART Statement in XCHART Statement: CUSUM Procedure. This chapter also provides syntax information and advanced examples.

If you are not familiar with cusum charts, read Formulas for Cumulative Sums Defining the Decision Interval for a One-Sided Cusum Scheme and Defining the V-Mask for a Two-Sided Cusum Scheme in the section Details: XCHART Statement. References lists articles and textbooks that provide more detailed information on cusum charts. The expository articles by Lucas (1976) and Goel (1982) and the textbooks by Montgomery (1996) and Ryan (1989) are recommended introductory reading.
