PROC CUSUM Statement |
After the PROC CUSUM statement, you provide an XCHART statement that specifies the cusum chart you want to create and the variables in the input data set that you want to analyze. For example, the following statements request a one-sided (decision interval) cusum chart:
proc cusum data=values; xchart weight*lot / scheme = onesided mu0 = 8.100 sigma0 = 0.050 delta = 1 h = 2.2 k = 0.5; run;
In this example, the DATA= option specifies an input data set (VALUES) that contains the process measurement variable WEIGHT and the subgroup-variable LOT. *
You can use options in the PROC CUSUM statement to
In addition to the XCHART statement, you can provide BY statements, ID statements, TITLE statements, and FOOTNOTE statements. If you are using a graphics device, you can also provide graphics enhancement statements, such as SYMBOLn statements, which are described in SAS/GRAPH Software: Reference.
Note: If you are using the CUSUM procedure for the first time, you should read both this chapter and "Getting Started" in Chapter 12, "XCHART Statement."
