Description

Classes for bounded, robust, standardized weights.

Objects from the Class

Objects can be created by calls of the form new("BdStWeight", ...); to fill slot weight, you will use the generating functions getweight and minbiasweight.

Slots

name

Object of class "character"; inherited from class RobWeight.

weight

Object of class "function" — the weight function; inherited from class RobWeight.

clip

Object of class "numeric" — clipping bound(s); inherited from class BoundedWeight.

stand

Object of class "matrix" — standardization.

Extends

Class "RobWeight", via class "BoundedWeight". Class "BoundedWeight", directly.

Methods

stand

signature(object = "BdStWeight"): accessor function for slot stand.

stand<-

signature(object = "BdStWeight", value = "matrix"): replacement function for slot stand. This replacement method should be used with great care, as the slot weight is not simultaneously updated and hence, this may lead to inconsistent objects.
