By default, PROC SURVEYSELECT displays two tables that summarize the sample selection: the "Sample Selection Method" table and the "Sample Selection Summary" table.

If you request sample allocation but no sample selection, PROC SURVEYSELECT displays two tables that summarize the allocation: the "Sample Allocation Method" table and the "Sample Allocation Summary" table.

You can suppress display of these tables by specifying the NOPRINT option.

PROC SURVEYSELECT creates an output data set that contains the units that are selected for the sample. Or if you request sample allocation but no sample selection, PROC SURVEYSELECT creates an output data set that contains the sample size allocation results. (See the sections Sample Output Data Set and Allocation Output Data Set for information about these output data sets.) The procedure does not display the output data set that it creates. Use PROC PRINT, PROC REPORT, or any other SAS reporting tool to display the output data set.

PROC SURVEYSELECT displays the following information in the "Sample Selection Method" table:

• Selection Method

• Sampling Unit Variables, if you specify a SAMPLINGUNIT statement

• Size Measure variable, if you specify a SIZE statement

• Size Measure: Number of Observations, if you specify the PPS option in the SAMPLINGUNIT statement and do not specify a SIZE statement

• Minimum Size Measure, if you specify the MINSIZE= option

• Maximum Size Measure, if you specify the MAXSIZE= option

• Certainty Size Measure, if you specify the CERTSIZE= option

• Certainty Proportion, if you specify the CERTSIZE=P= option

• Strata Variables, if you specify a STRATA statement

• Control Variables, if you specify a CONTROL statement

• type of Control Sorting (Serpentine or Nested), if you specify a CONTROL statement

• type of Allocation, if you specify the ALLOC= option in the STRATA statement

PROC SURVEYSELECT displays the following information in the "Sample Selection Summary" table:

• Input Data Set name

• Sorted Data Set name, if you specify the OUTSORT= option

• Random Number Seed

• Sample Size or Stratum Sample Size, if you specify the SAMPSIZE=n option

• Sample Size Data Set, if you specify the SAMPSIZE=SAS-data-set option

• Sampling Rate or Stratum Sampling Rate, if you specify the SAMPRATE=r option

• Sampling Rate Data Set, if you specify the SAMPRATE=SAS-data-set option

• Minimum Sample Size or Stratum Minimum Sample Size, if you specify the NMIN= option with the SAMPRATE= option

• Maximum Sample Size or Stratum Maximum Sample Size, if you specify the NMAX= option with the SAMPRATE= option

• Allocation Input Data Set name, if you specify the ALLOC=SAS-data-set option in the STRATA statement

• Variance Input Data Set name, if you specify the VAR=SAS-data-set option in the STRATA statement

• Cost Input Data Set name, if you specify the COST=SAS-data-set option in the STRATA statement

• Selection Probability, if you specify METHOD=SRS, METHOD=SYS, or METHOD=SEQ and do not specify a SIZE statement or a STRATA statement

• Expected Number of Hits, if you specify METHOD=URS and do not specify a STRATA statement

• Sampling Weight for equal probability selection methods (METHOD=SRS, METHOD=URS, METHOD=SYS, METHOD=SEQ) if you do not specify a STRATA statement

• Number of Strata, if you specify a STRATA statement

• Number of Replicates, if you specify the REPS= option

• Total Sample Size, if you specify a STRATA statement or the REPS= option

• Output Data Set name

If you specify the NOSAMPLE option in the STRATA statement, PROC SURVEYSELECT allocates the total sample among the strata but does not select the sample. When you specify the NOSAMPLE option, PROC SURVEYSELECT displays the "Sample Allocation Method" table, which includes the following information:

• Allocation method

• Strata Variables

When you specify the NOSAMPLE option in the STRATA statement, PROC SURVEYSELECT also displays the "Sample Allocation Summary" table, which includes the following information:

• Input Data Set name

• Allocation Input Data Set name, if you specify the ALLOC=SAS-data-set option in the STRATA statement

• Variance Input Data Set name, if you specify the VAR=SAS-data-set option in the STRATA statement

• Cost Input Data Set name, if you specify the COST=SAS-data-set option in the STRATA statement

• Number of Strata

• Stratum Minimum Sample Size, if you specify the ALLOCMIN= option in the STRATA statement

• Total Sample Size

• Allocation Output Data Set name
