BOXCHART Statement: ANOM Procedure
| Overview: BOXCHART Statement |
The BOXCHART statement creates an ANOM chart for group (treatment level) means of response values superimposed with box-and-whisker plots of the measurements in each group. Throughout this chapter, a chart of this type is referred to as an ANOM boxchart. You can use options in the BOXCHART statement to
compute decision limits from the data based on a specified parameters, such as the significance level (
) tabulate group sample sizes, group means, decision limits, and other information
save decision limits in an output data set
save group sample sizes and group means in an output data set
read decision limits and decision limit parameters from a data set
display distinct sets of decision limits for different sets of groups
specify one of several methods for calculating quantile statistics (percentiles)
control the style of the box-and-whisker plots
add block legends and symbol markers to identify special groups
clip extreme points to make the chart more readable
display vertical and horizontal reference lines
control axis values and labels
control layout and appearance of the chart
You have two alternatives for producing ANOM boxcharts with the BOXCHART statement:
ODS Graphics output is produced if ODS Graphics is enabled, for example by specifying the ODS GRAPHICS ON statement prior to the PROC statement.
Otherwise, traditional graphics are produced if SAS/GRAPH® is licensed.
See Chapter 3, SAS/QC Graphics, for more information about producing these different kinds of graphs.
