Hello, I am trying to analyze an imputed dataset. Everything runs okay except for proc mianalyze where I run into some problems. I am tyring to get pairwise differences of my class variable which has 3 categories. Here is the code that I am using: proc genmod data=mi_out; by _imputation_; /* Process each imputed dataset */ class matchid rand2; /* 'matchid' identifies matched pairs, 'treatment' is the variable of interest */ model DIFF = rand2 / dist=normal; /* 'outcome' is the continuous outcome */ repeated subject=matchid / type=cs; /* Matched pairs, compound symmetry */ /* Define pairwise comparisons using ESTIMATE statements */ estimate 'rand2_1_vs_rand2_2' rand2 1 -1 0; estimate 'rand2_1_vs_rand2_3' rand2 1 0 -1; ods output estimates=pairwise_estimates; /* Save estimates */ run; proc mianalyze parms=pairwise_estimates; modeleffects rand2_1_vs_rand2_2 rand2_1_vs_rand2_3 ; run; When I run the proc mianalyze, I get the following error: ERROR: Variable PARAMETER, EFFECT, VARIABLE, PARM, or ROWNAME must be in the PARMS= data set. can someone please help me understand why I am getting this error, or how I can obtain the pairwise differences?
