OUTTABLE= Data Set

The OUTTABLE= data set saves univariate statistics and capability indices. The following variables can be saved:

Note:The variables _CP_, _CPK_, _CPL_, _CPM_, _CPU_, _K_, _LSL_, _PCTGTR_, _PCTLSS_, _TARGET_, and _USL_ are included if you provide specification limits.

The OUTTABLE= data set and the OUT= data set¹ contain essentially the same information. However, the structure of the OUTTABLE= data set may be more appropriate when you are computing summary statistics or capability indices for more than one process variable in the same invocation of the CAPABILITY procedure. Each observation in the OUTTABLE= data set corresponds to a different process variable, and the variables in the data set correspond to summary statistics and indices.

[See CAPTAB1 in the SAS/QC Sample Library]For example, suppose you have ten process variables (P1-P10). The following statements create an OUTTABLE= data set named Table, which contains summary statistics and capability indices for each of these variables:

proc capability data=Process outtable=Table noprint;
  var P1-P10;
  specs lsl=5 10 65 35 35 5 25 25 60 15
        usl=175 275 300 450 550 200 275 425 500 525;
run;

The following statements create the table shown in Figure 5.4, which contains the mean, standard deviation, lower and upper specification limits, and capability index for each process variable:

proc print data=Table label noobs;
   var _VAR_ _MEAN_ _STD_ _LSL_ _USL_ _CPK_;
   label _VAR_='Process';
run;
