precision of integration

Is it possible to change the precision of the numerical integration for binary FIML? I don't get the same likelihood in classic versus OpenMx.

Thanks, Hermine.

To the extent that we're

To the extent that we're open-source, anything is customizable if you want it to be, but I haven't the slightest idea. There's nothing in ?mxOption, and the NPSOL manual isn't much help. Consider this a "bump."

Options available in OpenMx 2.0

To anyone reading this thread, a full set of options to control integration precision are now available. See thread

As of build 1515, it is not possible to specify precision on numerical integration. This is marked as a TODO, but hasn't been implemented quite yet.

You should still get results very close to what you got in classic--I believe we're using almost, if not precisely, identical settings.

Would you want this to be a global mxOption? An argument to mxFIMLObjective? Both?

Thanks for the feedback!
