You will not see any difference in OF or fit. Your eta1 is also rather small, and has large RSE. After you remove eta3, try to remove eta1 as well, you may found out that there is no difference (with the original model) either. One the other hand, eta2 is too large (do you use V=THETA(2) * EXP(ETA(2)) model ?). Try to use FOCE and study distribution of eta2: variance of eta2 is too large to accept the model without trying to find a better model or an explanation why this variance is so large. Good luck Leonid
