Hi, everyone.
I constructed a Cholesky ACE model. When I drop parameters, one submodel (after mxRun()) showed this error:
The job for model 'AE_Cholesky' exited abnormally with the error message: Objective function returned an infinite value.
How can I deal with it? (Other submodels of similar type which dropped different parameters did run.)
Adjust remaining free parameters
See my reply to your other post: http://openmx.psyc.virginia.edu/thread/857#comment-2891
Basically, you need to give the remaining free parameters decent starting values. Dropping a parameter runs a risk of there being little predicted variance remaining, which can cause the likelihood to be zero for one or more observations, which in turn generates a negative infinite log-likelihood.
