我正在尝试在SAS中运行此代码
proc mi data=Mono1 seed=1423741 nimpute=6 out=outex18;
class Trt;
monotone reg;
mnar adjust( y1 / adjustobs=(Trt='0') parms(shift=shift_c)=parm1);
adjust( y1 / adjustobs=(Trt='1') parms(shift=shift_t)=parm1);
var Trt y0 y1;
run;
但出现以下错误
ERROR: The _Imputation value is not a valid SAS name.
NOTE: The SAS System stopped processing this step because of errors.
WARNING: The data set WORK.OUTMI was only partially opened and will not be saved.
mnar也变成红色。
我该如何解决这个问题？
数据是

input trt y0 y1;
