Your OMEGA and SIGMA are too constrained. I tried this values (change for initial LAG) and it runs successful. $THETA (0,39,200) (0,325,10000) (0,8,200) (0,105,1000) (0,2,2000) (0,1,5) $OMEGA 5 5 5 $SIGMA 0.5 3 After a look to your data, I think that it is a 2-comp decline. Moreover, why do you use FOCE method ? Results are fine with FO.
