logLik.hglm {hglm}

Extracts log-likelihood values

Description

Extracts log-likelihood values from an existing hglm object hglm.obj.

Usage

## S3 method for class 'hglm'
logLik(object, REML=NULL, ...)

Arguments

object

A fitted hglm object.

REML

The default NULL returns all computed log-likelihoods. The option REML=TRUE returns only the adjusted profile log-likelihood profiled over fixed and random effects.

...

This argument is not used.

Details

The use of log-likelihoods and cAIC is described in Lee, Nelder and Pawitan (2006).

Value

A list of log-likelihood values for model selection purposes, where $hlik is the log-h-likelihood, $pvh the adjusted profile log-likelihood profiled over random effects, $pbvh the adjusted profile log-likelihood profiled over fixed and random effects, and $cAIC the conditional AIC.
