The UNIVARIATE Procedure

The OUTTABLE= data set saves univariate statistics in a data set that contains one observation per analysis variable. The following variables are saved:

The OUTTABLE= data set and the OUT= data set (see the section OUT= Output Data Set in the OUTPUT Statement) contain essentially the same information. However, the structure of the OUTTABLE= data set may be more appropriate when you are computing summary statistics for more than one analysis variable in the same invocation of the UNIVARIATE procedure. Each observation in the OUTTABLE= data set corresponds to a different analysis variable, and the variables in the data set correspond to summary statistics and indices.

For example, suppose you have 10 analysis variables (P1-P10). The following statements create an OUTTABLE= data set named Table, which contains summary statistics for each of these variables:

proc univariate data=Analysis outtable=Table noprint;
  var A1-A10;

The following statements create the table shown in Figure 4.15, which contains the mean, standard deviation, and so on, for each analysis variable:

proc print data=Table label noobs;
   var _VAR_ _MIN_ _MEAN_ _MAX_ _STD_;
   label _VAR_='Analysis';
run;
