deviance.spmodel: Fitted model deviance

Description

Returns the deviance of a fitted model object.

Usage

# S3 method for splm
deviance(object, ...)
# S3 method for spautor
deviance(object, ...)
# S3 method for spglm
deviance(object, ...)
# S3 method for spgautor
deviance(object, ...)

Value

The deviance.

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.

Examples

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