Class of (partial) influence curves of Hampel (= total variation or contamination) type;
used as common mother class for classes ContIC
and TotalVarIC
.
Objects can be created by calls of the form new("HampIC", ...)
.
CallL2Fam
object of class "call"
:
creates an object of the underlying L2-differentiable
parametric family.
name
object of class "character"
Curve
object of class "EuclRandVarList"
modifyIC
object of class "OptionalFunction"
:
function of four arguments: (1) L2Fam
an L2 parametric family
(2) IC
an optional influence curve, (3) withMakeIC
a logical argument whether to enforce the IC side conditions
by makeIC
, and (4) ...
for arguments to be passed to
calls to E
in makeIC
. Returns an object of
class "IC"
. This function is mainly used for internal
computations!
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.
stand
object of class "matrix"
:
standardizing matrix.
weight
object of class "RobWeight"
:
weight function
biastype
object of class "BiasType"
:
bias type (symmetric/onsided/asymmetric)
normtype
object of class "NormType"
:
norm type (Euclidean, information/self-standardized)
lowerCase
object of class "OptionalNumeric"
:
optional constant for lower case solution.
neighborRadius
object of class "numeric"
:
radius of the corresponding (unconditional) contamination
neighborhood.
Class "IC"
, directly.
Class "InfluenceCurve"
, by class "IC"
.
signature(object = "HampIC")

.
signature(object = "HampIC")
:
replacement function for slot neighborRadius
.
signature(object = "ANY")
:
returns NULL
