I want to sample without replacement two data set that are complement in ratio 2:1 from the data. Data set "A" should be n=17 and the remaining n=9 should be data set "B"
DATA hsb25; INPUT id gender $ race ses schtype $ prog read write math science socst; DATALINES; 147 f 1 3 pub 1 47 62 53 53 61 108 m 1 2 pub 2 34 33 41 36 36 18 m 3 2 pub 3 50 33 49 44 36 153 m 1 2 pub 3 39 31 40 39 51 50 m 2 2 pub 2 50 59 42 53 61 51 f 2 1 pub 2 42 36 42 31 39 102 m 1 1 pub 1 52 41 51 53 56 57 f 1 2 pub 1 71 65 72 66 56 160 f 1 2 pub 1 55 65 55 50 61 136 m 1 2 pub 1 65 59 70 63 51 88 f 1 1 pub 1 68 60 64 69 66 177 m 1 2 pri 1 55 59 62 58 51 95 m 1 1 pub 1 73 60 71 61 71 144 m 1 1 pub 2 60 65 58 61 66 139 f 1 2 pub 1 68 59 61 55 71 135 f 1 3 pub 1 63 60 65 54 66 191 f 1 1 pri 1 47 52 43 48 61 171 m 1 2 pub 1 60 54 60 55 66 22 m 3 2 pub 3 42 39 39 56 46 47 f 2 3 pub 1 47 46 49 33 41 56 m 1 2 pub 3 55 45 46 58 51 128 m 1 1 pub 1 39 33 38 47 41 36 f 2 3 pub 2 44 49 44 35 51 53 m 2 2 pub 3 34 37 46 39 31 26 f 4 1 pub 1 60 59 62 61 51 ; RUN;
. The code below create data "A", but out to I output the remaining and call it "B"?
proc surveyselect data = hsb25 method = SRS rep = 1 sampsize = 17 seed = 12345 out = A; id _all_; run;
If you use the OUTALL option on the proc statement all records in the data set will be output and an additional variable named Selected will be in the data. A value of 1 for selected indicates the records selected and 0 is not selected.
Depending on what you are actually doing next you could split the data using that variable or use Where clauses or By group processing with that data set.
proc surveyselect data = hsb25 method = SRS outall rep=1 sampsize = 17 seed = 12345 out = A; id _all_; run; data seta setb; set A; if selected=1 then output seta; else output setb; run;
I don't think you're actually gaining anything with the REP=1.
BTW your example data only has 25 records so we can't get 17 and 9.
