I wonder if anyone have come across similar problem like me?
This information always appears after I build up my model:
Model execution failed
"out of range final -LL value 1.0000000001E+070"
I use FOCE-ELS, and this is the model that have been developed with good fixed parameter and good AIC. And I only change a little bit of the initial parameters (say change 30 to 35), or adding covariate, so I don't think this is because I didn't choose a good set of initial values.
The other thing is that in the NLME Job Status TAB, I can see the the 2LL value is going down and close to what I usually get. So the "out of range final -LL value" information doesn't make any sense to me.
I have changed the algorithm to naive pooled or other method and change it back to FOCE-ELS, but this message still came up and the calculation stoped.
So any suggestion for this problem, should I try to adjust parameters in the running mode?
