intervals using boot::boot() (instead of
lmer::bootMer()) when ci_method = "boot" or
analytical confidence intervals (ci_method = "analytical").

compute confidence intervals and use

be calculated at all. Note that the default computation method is
preferred.

argument (smoothing bandwidth), which is passed down to the
plot() methods density-estimation.

type is set to "default" for models without
discrete outcomes, and else
type = "discrete_interval".

intervals, and reports those by default (the standard error is no longer

models from packages metafor and meta.
