Hello,

I was successfully able to impute my data, but I get the following error when I reach the mi estimate step:

Code:
mi set wide
mi register imputed testscore
mi impute chained (regress) testscore = x1 x2 x3 i.school i.id, add(20) force noisily
mi estimate: mixed testscore x y Month ||school: ||id:, covariance(unstructured) reml dfmethod(kroger)
mi estimate does not support mixed, dfmethod() r(198);

mi estimate works fine when I remove dfmethod(), but this is essential for correcting the degrees of freedom. Is there a way around this?
