I just upgraded to the newest version of OpenMx and R 2.15.0. I ran a simple univariate script and everything worked fine until the AE model. This is the error I get when I run the univAEFit:
Error: Unknown reference to 'AE.VarComp' detected in a confidence interval specification in model 'univAE' in runHelper(model, frontendStart, intervals, silent, suppressWarnings, unsafe, checkpoint, useSocket, onlyFrontend, useOptimizer).
However, setting intervals=F, the function runs properly and I can obtain statistics for the AE model.
I used the same script/data files on another PC - running the previous version of OpenMx and R 2.14.1 and the script runs without problems for all the three models. With the newer version, the BIC value for the Saturated, full ACE and the AE model is double the one I obtained with the previous version.
I think I have installed the required packages with all the dependencies... I am not sure what is going wrong...
Thanks for your help,
