I am currently trying to recreate ClassicMx script for an ECOT model into OpenMx and I am coming across an error that I am not sure how to solve.
When I run the model I get the following error:

Error: The following error occurred while evaluating the subexpression 'solve(ecot.matF %% solve(ecot.matI - ecot.matA) %% ecot.matM %*% ecot.matU)' during the evaluation of 'MZtoss.expMeanMZtoss' in model 'modelECOT' : 'a' (4 x 1) must be square

I have attached the ClassicMX code and OpenMx code.

extraneous solve()

There is an extraneous solve() operation in the MxAlgebras that define the model-expected means. I think what you probably want to do is


, although I don't really understand what the 'U' matrix is supposed to do.
