Sorry, I have overlooked this post. If you want to avoid centering for `sigma` as well, or specify other arguments, you need to replace `sigma ~ Days + (Days | Subject)` by `lf(sigma ~ Days + (Days | Subject), center = FALSE)`.

Now that I think of it, it may be more intuitive if the global `center` etc. arguments applied to all formulas, but I need to think more of that.
