Extract Log-Likelihood from mlmodel objects

Usage

# S3 method for class 'mlmodel'
logLik(object, ...)

# S3 method for class 'summary.mlmodel'
logLik(object, ...)

Arguments

object

An object of class mlmodel or summary.mlmodel.

...

Additional arguments passed to methods.

Value

An object of class "logLik" with the log-likelihood value and the attributes nobs and df.

Details

The returned object is of class "logLik" and has two important attributes:

  • nobs: number of observations used in estimation.

  • df: number of estimated parameters (usually called K), computed as length(coef(object)). This includes coefficients from both the location (mean/value) and scale equations when present.
