abnormally error

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:

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.
