add_ic: Add information criteria and fit indices to fitted model objects

Description

Add information criteria and fit indices to fitted model objects

Usage

add_ic(x, ...)

add_ic(x, ...) <- value

# S3 method for brmsfit
add_ic(x, ic = "loo", ...)

Arguments

x

An R object typically of class brmsfit.

...

Further arguments passed to the underlying
functions computing the information criteria.

ic, value

Names of the information criteria / fit indices
to compute. Currently supported are "loo",
"waic", "kfold", "R2" (R-squared), and
"bridge" (log marginal likelihood).

Value

An object of the same class as x, but
with information criteria added for later usage.
