Answer Posted / srikanth
you can use the RANUNI function to select observations
randomly.
Ex:-
data test;
input number @@;
cards;
2.1 3.1 4 6 2.2 4.9 4 5 3 3.3 4 5 3 4.3 5 7 3 3 9 11
;
data test1;
set test;
random=ranuni(1);
run;
%let k=10;
PROC SORT DATA=TEST1;
BY random;/*SORT OBSERVATIONS*/
run;
DATA TEST2;
SET TEST2 (DROP=RANDOM);
IF _N_ LE &K;
RUN;
PROC PRINT ;
RUN;
