CondTotalVarIC-class: Conditionally centered influence curve of total variaton type

Description

Class of conditionally centered (partial) influence curves of contamination type for average conditional total variation $$\eta = max(c(x), min(A x\Lambda_f, b(x)))$$ with lower clipping function \(c\), upper clipping function \(b\) and standardizing matrix \(A\). \(\Lambda_f\) stands for the L2 derivative of the corresponding error distribution.

Objects from the Class

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

clipUp:

object of class "RealRandVariable": upper clipping function.

clipLo:

object of class "RealRandVariable": lower clipping 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 conditional contamination neighborhood.

neighborRadiusCurve:

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

Extends

Class "CondIC", directly. Class "IC", by class "CondIC". Class "InfluenceCurve", by class "CondIC".
