Av1CondContIC-class: Conditionally centered influence curve of contamination type

In ROptRegTS: Optimally Robust Estimation for Regression-Type Models

Description

Class of conditionally centered (partial) influence curves of contamination type for average conditional contamination neighborhoods; i.e., influence curves eta of the form

eta = (A Lambda - a)min(1, b/|A Lambda - a|)

with clipping bound b, centering function a and standardizing matrix A. Lambda stands for the L2 derivative of the corresponding L2 differentiable regression type family created via the call in the slot CallL2Fam.

Objects from the Class

Objects can be created by calls of the form new("Av1CondContIC", ...). More frequently they are created via the generating function Av1CondContIC, respectively via the method generateIC.

Slots

CallL2Fam:

object of class "call": creates an object of the underlying L2-differentiable regression type family.

name:

object of class "character"

Curve:

object of class "EuclRandVarList"

Risks:

object of class "list": list of risks; cf. RiskType-class.

Infos:

object of class "matrix" with two columns named method and message: additional informations.

clip:

object of class "numeric": clipping bound.

cent:

object of class "EuclRandVarList": centering function.

stand:

object of class "matrix": standardizing matrix.

lowerCase:

object of class "OptionalNumeric": optional constant for lower case solution.

neighborRadius:

object of class "numeric": radius of the corresponding average conditional contamination neighborhood.
