Hi, everyone! An update to the question. Since my problem here is simply the forms of input data in the 'modeleffects' syntax in PROC MIANALYZE, I tried to create a dataset containing parameter estimates, standard error and 95% confidence intervals of the NDE, NIE and so on separately by _imputation_ numbers. It works! Below is the screenshot of my self-made input data, and the result of PROC MIANALYZE. Still I'm not quite sure of the results. Can anyone judge whether my way is right or not? (@SAS_Rob for help!) Thanks!
