Hi,

I was wondering about some lower bound NaN values I've come across (or also when, for example the AE model has C set to 0, but the variance component has a lower bound CI NaN value even though all of them should have a value of 0 (lower bound, estimate, upper bound)). Specifically, I have had NaN values for the A standardized variance component lower bound of the confidence interval from time to time. Does anyone know why this may be? Is there a work-around on how to adjust it? It's for relatively few estimates, but it does come up.

I am using the latest OpenMx version and it seems to be running fine otherwise in general (on a univariate model, etc.).

I know there is also calculating a CI via bootstrapping, but I am not entirely sure how to do that as of yet (but maybe that would lend itself toward resolving this issue).

Definitely appreciate any advice!
