Hi Listers, 

I am running a regression analysis using xtmixed where I adjust the outcome using baseline measures on data which I have imputed using mi ice. 

I don't seem able to combine the mi estimate command with tabstat/adjust commands - even after specifying the cmdok subcommand (below).  

xi: mi estimate: xtmixed fQPR_tot bQPR_tot i.Intervention  || team: , mle  cov(uns)

mi estimate, cmdok: tabstat fQPR_tot, by(Intervention) stat(mean sdmean)

mi estimate, cmdok: adjust bQPR_tot , by(Intervention ) se

I receive the folloiwubg error message: 

matrix e(b) is not set
matrix e(V) is not set

is there any way around so that I can estimate adjusted means on the imputed data?
