## Extract Random Effects

### Description

Extract random effects from objects fitted with the function 'glmm.admb'
and (optionally) their standard deviations.

### Usage

ranef.glmm.admb(object, sd = FALSE)

### Arguments

`object` |
An object (a fit) returned from `glmm.admb` |

`sd` |
logical. If 'TRUE', the standard deviations of the random effects are
returned, rather than point estimates. |

`...` |
Further arguments passed on |

### Details

The point estimates of the random effects are 'empirical Bayes' estimates in
the sense that the hyperparameters (fixed effects, variance components etc) are fixed
at their MLE's when the joint likelihood is maximized with respect to the random effects.
However, uncertainty about the hyperparameters is taken into account when the
standard deviations of the random effects are calculated.

### Value

A matrix of estimated random effects (or standard deviations).
