| HampelWeight-class {RobAStBase} | R Documentation |
Classes for weights of Hampel type.
Objects can be created by calls of the form new("HampelWeight", ...);
to fill slot weight, you will use the generating functions
getweight and minbiasweight.
name:"character"; inherited from class RobWeight. weight:"function" — the weight function; inherited from class RobWeight.clip:"numeric" — clipping bound(s); inherited from class BoundedWeight.stand:"matrix" — standardization; inherited from class BdStWeight.cent:"numeric" — centering.
Class "RobWeight", via class "BoundedWeight".
Class "BoundedWeight", via class "BdStWeight".
Class "BdStWeight", directly.
signature(object = "HampelWeight"):
accessor function for slot cent. signature(object = "HampelWeight", value = "matrix"):
replacement function for slot cent. 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. Peter Ruckdeschel Peter.Ruckdeschel@itwm.fraunhofer.de
