Hello,
I'm running a relatively complex model with binary outcomes (but well under the max 20 ordinal vars). I'm fixing mean=0, var=1 and letting thresholds vary. Things periodically fail with:
error in runHelper(model, frontendStart, intervals, silent, suppressWarnings, : xn out of range
Starting values can seem to cause this (even when mxTryHardOrdinal is jiggling around values close to the optimum some tries will fail out with this), also increasing complexity (doing a multiple groups analysis), also sometimes decreasing mvnRelEps will cause this.
Any ideas of what might be going on or how to debug this further?
Thanks for the help!
