BOXCHART Statement: ANOM Procedure

Saving Summary Statistics for Groups

Note: See Saving Summary Statistics for Groups in the SAS/QC Sample Library.

In this example, the BOXCHART statement is used to create a data set containing group summary statistics that can be read later by the ANOM procedure (as in the preceding example). The following statements read measurements from the data set LabelDeviations and create a summary data set named LabelSummary: 

proc anom data=LabelDeviations;
   boxchart Deviation*Position / outsummary=LabelSummary
                                 nochart;
run;

The OUTSUMMARY= option names the output data set, and the NOCHART option suppresses the display of the chart, which would be identical to Figure 4.3.

Figure 4.6 contains a listing of LabelSummary.

There are nine variables in the data set LabelSummary. 
            

            

               
    

  • 
                     
    Position identifies the group. 
                     
    
                  
    •

    • 
                  
  • 
                     
    DeviationM contains the group medians. 
                     
    
                  
    • 
                  
  • 
                     
    Deviation3 contains the third quartile for each group. 
                     
    
                  
    • 
                  
  • 
                     
    DeviationH contains the group maximums. 
                     
    
                  
    • 
                  
  • 
                     
    DeviationS contains the group standard deviations. 
                     
    
                  
    • 
                  
  • 
                     
    DeviationN contains the group sizes. 
                     
    
                  
    • 
               



            

               
               
               Note that the summary statistic variables are named by adding the suffix characters L, 1, X, M, 3, H, S, and N to the response Deviation specified in the BOXCHART statement. In other words, the variable naming convention for OUTSUMMARY= data sets is the same
               as that for SUMMARY= data sets.
