There are no intervals for random effects for nlme, because it doesn't provide even a standard error to calculate them with. In the helpfile for extract_random_effects
it states "The nlme package only provides the estimated random effect parameters, not their uncertainty, so it isn't provided."
The brms package may be able to do this type of model for you, at which point you should be able to get the interval estimate from extract_random_effects
.
Going ahead and closing as the function is working as documented, but feel free to post if something else is amiss.
mixedup::extract_random_efects does not report condfidence intervals for nlme object. It is not working for nonlinear models even though the documentation inform that fucntion can handle with this objects.
