Description
I am having trouble understanding the behaviour of parameters()
on lme objects under different specifications of the random effects (corresponding to method (i) and (iv) in the lme documentation of the random =
argument).
When the random effect is specified using formula with pipe for grouping, parameters behaves as expected,
library("nlme")
library("parameters")
lme(weight ~ Treatment,
random = ~ 1 | Litter,
data = RatPupWeight) |>
parameters()
However, parameters fail on the same model specified with a list (the names indicating the grouping),
lme(weight ~ Treatment,
random = list(Litter = ~ 1),
data = RatPupWeight) |>
parameters()
