Extract AIC from mlmodel objects — AIC.mlmodel • mlmodels

Extract AIC from mlmodel objects

Usage

# S3 method for class 'mlmodel'
AIC(object, ..., k = 2)

# S3 method for class 'summary.mlmodel'
AIC(object, ..., k = 2)

Arguments

object: An object of class "mlmodel" or "summary.mlmodel".
...: Further arguments passed to methods.
k: Numeric. The penalty per parameter. Default is k = 2 (standard AIC). See stats::AIC() for details.

Value

A numeric value with the AIC.

Details

For mlmodel objects, AIC is computed as -2 * logLik(object) + k * npar.

For summary.mlmodel objects, the pre-computed AIC (with k = 2) is returned; the k argument is accepted for compatibility but ignored.
