SURVEYSELECT Procedure


The OUTALL option produces an output data set that includes all observations from the DATA= input data set, both those observations selected for the sample and those observations not selected . With the OUTALL option, the OUT= data set contains a variable Selected that indicates whether or not the observation was selected. The OUTALL option is available for equal probability selection methods (METHOD=SRS, URS, SYS, and SEQ).

The SELECTALL option includes all stratum observations in the sample when the stratum sample size exceeds the number of observations in the stratum. The SELECTALL option is available for without-replacement selection methods (METHOD=SRS, SYS, SEQ, PPS, and PPS_SAMPFORD). It is not available for with-replacement or with-minimum-replacement methods, or for those PPS methods that select two units per stratum.
