HampIC-class {RobAStBase} | R Documentation |
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
:"call"
:
creates an object of the underlying L2-differentiable
parametric family. name
:"character"
Curve
:"EuclRandVarList"
modifyIC
:"OptionalFunction"
:
function of two arguments, which are an L2 parametric family
and an optional influence curve. Returns an object of
class "IC"
. This slot is mainly used for internal
computations! Risks
:"list"
:
list of risks; cf. RiskType-class
. Infos
:"matrix"
with two columns named method
and message
:
additional informations. stand
:"matrix"
:
standardizing matrix. weight
:"RobWeight"
:
weight function biastype
:"BiasType"
:
bias type (symmetric/onsided/asymmetric) normtype
:"NormType"
:
norm type (Euclidean, information/self-standardized)lowerCase
:"OptionalNumeric"
:
optional constant for lower case solution. neighborRadius
:"numeric"
:
radius of the corresponding (unconditional) contamination
neighborhood.
