data a;
infile "work.b";
input x y @ @;
proc mi data=a seed=1000 output=outb;
run;
程序就是这样编的 然后我去work里看结果的时候 系统说“ERROR: Variable list empty.
NOTE: The SAS System stopped processing this step because of errors.
WARNING: The data set WORK.OUTB may be incomplete. When this step was stopped there were 0 observations and 0 variables.”
请各位指点一下我的问题出在哪里。
