anova.elliptical: Analysis of Deviance for Elliptical Model Fits

Description

Compute an analysis of deviance table for one or more elliptical model fits.

Usage

# S3 method for elliptical

  test = c("Chisq"), ...)

Arguments

object

fit object for elliptical regression model.

dispersion

the dispersion parameter for the fitting family, by default obtained from object.

test

a character string representing that hypothesis test should be considered.

...

arguments to be used to form the default control argument if it is not supplied directly.
