Hello, I am trying to use PROC MI to impute values in a data set, there are not many missing values in the data set, but a fair number of variables. When I just use PROC MI without the VAR statement, it doesn't appear to analyze all the variables. When I specify the variables, I'm fine specifying up to 8, but when I add the ninth variable, I get an error "Variable att9 should either be numeric in the CLASS list" Is there a parameter that I need to add to expand the variable list? I'm using: proc mi data=newdata seed=33333 out=midata; var att1 att2 att3 att4 att5 att6 att7 att8 att9; run; Thanks.
