I was wondering whether you could point me to information about how to pass algebraic statements to OpenMx via the osmasem function so that I can test indirect effects – in tssem2 this is done easily, but it’s not so obvious with osmasem. The documentation for osmasem doesn't seem to go into detail about this. I suspect it could be done with the mxModel.args option, but as I don’t know my way around OpenMx all that well I had trouble figuring out how…
Thanks!
