deviance.spmodel {spmodel}

Fitted model deviance

Description

Returns the deviance of a fitted model object.

Usage

## S3 method for class 'splm'
deviance(object, ...)

## S3 method for class 'spautor'
deviance(object, ...)

## S3 method for class 'spglm'
deviance(object, ...)

## S3 method for class 'spgautor'
deviance(object, ...)

Arguments

object

A fitted model object from splm(), spautor(), spglm(), or spgautor(), where estmethod is "ml" or "reml".

...

Other arguments. Not used (needed for generic consistency).

Details

For objects estimated using "ml" or "reml", the deviance is twice the difference in log-likelihoods between the saturated (perfect-fit) model and the fitted model.

Value

The deviance.

Examples

spmod <- splm(z ~ water + tarp,
  data = caribou,
  spcov_type = "exponential", xcoord = x, ycoord = y
)
deviance(spmod)
