The NPAR1WAY Procedure

Output Data Set

The OUTPUT statement creates a SAS data set that contains statistics computed by PROC NPAR1WAY. You specify which statistics to store in the output data set by using options identical to those in the PROC NPAR1WAY statement. When you specify one of these options in the OUTPUT statement, PROC NPAR1WAY includes all available statistics from that analysis in the output data set.

The output data set contains one observation for each analysis variable within a BY group. (You can name the analysis variables in the VAR statement.) The OUTPUT data set includes the following variables:

  • BY variables, if you use a BY statement

  • _VAR_, which identifies the analysis variable

  • Variables containing the specified statistics

Table 62.5 lists the variable names and descriptions for all available statistics. Note that some statistics are available only for the two-sample case (where the CLASS variable groups the data into two classes); other statistics are available only for the multisample case.

If you request exact tests by using the EXACT statement, the output data set also includes exact p-values for those tests when you specify the corresponding options in the OUTPUT statement. If you do not request exact tests with the EXACT statement, the output data set does not include exact p-values.

Monte Carlo estimates of exact p-values are not available in this output data set, but you can use the Output Delivery System (ODS) to store Monte Carlo estimates in a SAS data set. You can use the Output Delivery System to create a SAS data set from any piece of PROC NPAR1WAY output. For more information, see the section ODS Table Names and Chapter 20, Using the Output Delivery System.
