glm.summaries: Accessor functions for objects the class "glm"

Description

Covariance matrix of the coefficient estimates, rank, scale estimate and the weights for class "glm" objects. All these functions are methods.

Usage

# S3 method for glm
covar(object)
 
# S3 method for glm
Rank(object)
 
# S3 method for glm
rscale(object)
 
# S3 method for glm
weights(object)

Arguments

object

An object inheriting from class "glm".
