I'm having some trouble and have been getting an error message that reads:
"Error: The RAM model 'MZ' does not contain a RAM objective function."
What has me perplexed is that I specify what OpenMx should take into account when evaluating the model (for both groups in a BG study):
mxFIMLObjective(covariance="R", means="M", dimnames=manifests, thresholds="expThresholds")
mxAlgebra(expression=MZ.objective + DZ.objective, name="minus2sumll" ),
Thank you for any insight.
UPDATE: I figured it out. The error (which should have been obvious) is that I mislabeled the model type.
