deviance.spmodel function

Fitted model deviance

Returns the deviance of a fitted model object.

## 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).

Returns

The deviance.

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)
