Proc MI Impute flag

I want to compare the observed vs imputed values from Proc MI. Is there an easy way to identify the imputed values in the output dataset?

I assume you are talking about the data set created by the OUT= option on the PROC MI statement.

That data set does not contain a copy of the original data. It contains N copies of the imputed data.

If you need the original data, you could prepend it to the imputed data. Maybe set _imputation_=0 to identify it, like this:

data Original;
_imputation_ = 0;
set Original; 
run;

data All;
set Original OutMI;
run;
