Learning about the CUSUM Procedure

Introduction

If you are using the CUSUM procedure for the first time, begin by reading Chapter 11, "PROC CUSUM Statement," to learn about input data sets. Then turn to "Getting Started" in Chapter 12, "XCHART Statement." 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 "Details" section. The "References" section 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.
