I have a dataset including students from three districts (n=629), two districts implemented a math intervention and one district did not. I ran CEM to match students at districts receiving the math intervention to those at the district that did not implement the intervention. The mathematics assessment scale score is my outcome.
To account for nesting at the district level, I'm using the mixed command. However, when I add the CEM iweights to the mixed command, I get an error message stating that iweights are not allowed. How can I utilize weights from CEM but also account for district nesting of students?
mixed scalescore treatment [iweight=cem_weights] || districtnumber:,
iweights not allowed
r(101);
Thanks in advance!
