anova.elliptical: Analysis of Deviance for Elliptical Regression Models

In gwer: Geographically Weighted Elliptical Regression

Description

Compute an analysis of deviance table for the fitted elliptical regression model.

Usage

## S3 method for class 'elliptical'
anova(object, ..., dispersion = NULL, test = c("Chisq"))

Arguments

object	an object with the result of the fitted elliptical regression model.
...	arguments to be used to form the default control argument if it is not supplied directly.
dispersion	the dispersion parameter for the fitting family. By default it is obtained from the object.
test	a character string indicating the hypothesis test considered. Only chi-square test is implemented at moment.

Value

Return an object of class “anova”. This object contain the analysis of deviance table.
