I am quite new to behavioral genetic modelling and I have a question about an error that I am receiving since the OpenMX update.
I have used the same scripts as before the update, but my results are very different.
in addition, I now get the error:
In model 'ACE' Optimizer returned a non-zero status code 6. The model does not satisfy the first-order optimality conditions to the required accuracy, and no improved point for the merit function could be found during the final linesearch (Mx status RED)
Does anyone else received this message since the update?
Is there a way to solve it?
My data and scripts are attached.
The "old" results were: A=0,55 C=0 E=0,45, AIC= 252,12
Many thanks in advance!
