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
Object of class "character"
; inherited from class RobWeight
.
weight
Object of class "function"
--- the weight function; inherited from class RobWeight
.
clip
Object of class "numeric"
--- clipping bound(s); inherited from class BoundedWeight
.
stand
Object of class "matrix"
--- standardization; inherited from class BdStWeight
.
cent
Object of class "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.
