I have been working my way through a number of examples from a couple of books implementing them in OpenMx in order to learn how it works. So far so good. I now want to move on to using categorical/ordinal manifest variables. The examples I have found on this web site either in the formal documentation or in the forums all seem to do this using the matrix specification. Is there any fatal flaw in trying to do this using the path type specification (which I find more congenial)? I understand that I could part specify the model using the path method and then dump out the matrices but that seems a bit inelegant even if it is true. Of course if the answer is ' You looked in the wrong place' then a pointer would be helpful.
