I need your help.
I have a panel data with ar 1.
I estimate with the command xtmixed the following expression:
xtmixed vardep var_indep1 var_indep2 || u : var_indep2 , residuals (ar
where u is the random error component
and I want the random slope in the var_indep2
Could someone tell me, please, why Stata reports me an error (invalid
something: unmatched close parenthesis or bracket) in my expression?
I appreciate it
