PROC MACONTROL Statement

Overview

The PROC MACONTROL statement starts the MACONTROL procedure and it identifies input data sets.

After the PROC MACONTROL statement, you provide either an EWMACHART or an MACHART statement that specifies the type of moving average 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 uniformly weighted moving average chart:

   proc macontrol data=values;
      machart weight*lot / mu0    = 8.10
                           sigma0 = 0.05
                           span   = 5;
   run;

In this example, the DATA= option specifies an input data set named VALUES that contains the process measurement variable WEIGHT and the subgroup-variable LOT. ^*

You can use options in the PROC MACONTROL statement to

specify input data sets containing variables to be analyzed, parameters for calculating moving averages, or annotation information
specify a graphics catalog for saving graphical output
specify that charts are to be produced on graphics devices or line printers
define characters used for features on charts produced on line printers

In addition to the chart 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 MACONTROL procedure for the first time, you should also read the "Getting Started" section of Chapter 20, "EWMACHART Statement," and the "Getting Started" section of Chapter 21, "MACHART Statement."
