Description

Class of finite-sample Hampel risk which is the trace of the finite-sample covariance subject to a given bias bound (bound on gross error sensitivity).

Objects from the Class

Objects can be created by calls of the form new("fiHampel", ...). More frequently they are created via the generating function fiHampel.

Slots

type

Object of class "character": “trace of finite-sample covariance for given bias bound”.

bound

Object of class "numeric": given positive bias bound.

Extends

Class "fiRisk", directly.
Class "RiskType", by class "fiRisk".

Methods

bound

signature(object = "fiHampel"): accessor function for slot bound.
