This is extraction from Proc SURVEYSELECT help: <BR /> <BR /> OUTALL <BR /> includes all observations from the input data set in the output data set. By default, the output data set includes only those observations selected for the sample. When you specify the OUTALL option, the output data set includes all observations from DATA= and also contains a variable to indicate each observation's selection status. The variable Selected equals 1 for an observation selected for the sample, and equals 0 for an observation not selected. For information on the contents of the output data set, see the section "Output Data Set." <BR /> <BR /> Sincerely,<BR /> SPR Thu, 02 Dec 2010 15:02:21 GMT SPR 2010-12-02T15:02:21Z https://communities.sas.com/t5/SAS-Procedures/Removing-random-sample-obs-from-sampling-frame-after-using-Proc/m-p/42709#M11109 I need to generate a random sample of 50 individuals from a sampling frame dataset. I did this using proc surveyselect....now, of those 50 random individuals, I need to remove them from the sampling frame now so if I drawn another random sample that don't have the chance to be included again....how would I go about removing the random generated sample from the sampling frame after they are chosen?
