proc surveyselect

[deleted_user]

i would like to output multiple sample datasets using proc surveyselect.

That's to create 3 sample datasets with a 30,20,50 split from the original dataset.

Thanks and regards,
Thabiso

I'm not sure but I don't think it is possible to output more than one sample data set from PROC SURVEYSELECT. However you can do even better and create three samples in the same data set.

[pre]
proc surveyselect data=sashelp.class out=class3 rate=1 rep=3;
run;
proc surveyselect data=class3 out=sample3 n=(3,2,5);
strata rep:;
run;
proc print;
run;
[/pre]

It base what method you want?

Such as simple random sample.
[pre]
proc surveyselect data=.. out=... method=srs sample_size=50;
run;
