updateNorm-methods: Methods for Function updateNorm in Package `ROptEst'

Description

updateNorm-methods to update norm in IC-Algo

Usage

updateNorm(normtype, ...)
# S4 method for SelfNorm
updateNorm(normtype, L2, neighbor, biastype, Distr, V.comp, 
                                cent, stand,  w)

Value

updateNorm

an updated object of class NormType.

Arguments

normtype

normtype of class NormType

...

further arguments to be passed to specific methods.

L2

L2derivative

neighbor

object of class "Neighborhood".

biastype

object of class "BiasType"

cent

optimal centering constant.

stand

standardizing matrix.

Distr

standardizing matrix.

V.comp

matrix: indication which components of the standardizing matrix have to be computed.

w

object of class RobWeight; current weight

Methods

updateNorm

signature(normtype = "SelfNorm"): udates the norm in the self-standardized case; just used internally in the opt-IC-Algorithm.

Author

Peter Ruckdeschel

Details

updateNorm is used internally in the opt-IC-algorithm to be able to work with a norm that depends on the current covariance (SelfNorm)
