Hi,
I have attached a bivariate ACE two group twin model script.
I don't seem to be getting the expected behavior when attempting to drop paths using mxMatrix
If i try and fix the cells of the 'e' matrix to zero, I get the error
# ERROR in paste("The job for model", omxQuotes(flatModel@name), "exited abnormally with the error message:", :
# cannot coerce type 'char' to vector of type 'character'
As of revision 810, the error
As of revision 810, the error message generated by the model is: "The job for model 'twinAC' exited abnormally with the error message: Covariance matrix is not positive-definite". With regards to whether or not the AC model has been specified correctly, I don't know the answer to that question.
