I am using mimrgns after mi estimate and keep getting this message for one of the analysis
There are observations that have the combination of x=0 y=0 z=0 u=0 v=0 and I don't understand where the error comes from
any help would be much appreciated
Thank you
Code:
mi estimate: regress vm time i.x i.y i.z i.u i.v mimrgns, over(time) at(x=0 y=0 z=0 u=0 v=0) cmdmargins post conformability error an error occurred when mi estimate executed mimrgns_estimate on m=18
any help would be much appreciated
Thank you
