residuals.liu: Liu Regression Residuals

Description

The residuals function computes the Liu residuals for scalar or vector value of biasing parameter \(d\).

Usage

# S3 method for liu
residuals(object, …)

Arguments

object

An object of class "liu".

…

Not presently used in this implementation.

Value

Returns a vector or a matrix of the Liu residuals for scalar or vector value biasing parameter \(d\) provided as argument to liu function.

Details

The generic functions residuals can be used to compute residuals of object of class "liu" from function liu.
