| 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.
Class "IC", directly.
Class "InfluenceCurve", by class "IC".
signature(object = "HampIC"):
accessor function for slot stand. signature(object = "HampIC"):
accessor function for slot weight. signature(object = "HampIC"):
accessor function for slot biastype. signature(object = "HampIC"):
accessor function for slot normtype. signature(object = "HampIC"):
accessor function for slot lowerCase. signature(object = "HampIC"):
accessor function for slot neighborRadius. signature(object = "HampIC"):
replacement function for slot neighborRadius.
