Hi George, Hm, sorry about that. It seems to be saying that the parameter uncertainties weren't calculated correctly. It probably should not even be trying to estimate the uncertainty in the model. I believe it should be fixed in git master for larch, and I'll see about looking for this in lmfit too.
