| ContIC-class {ROptEst} | R Documentation |
Class of (partial) influence curves of contamination type; i.e., influence curves eta of the form
eta = (A Lambda - a)min(1, b/|A Lambda - a|)
with clipping bound b, centering constant a and
standardizing matrix A. Lambda stands for
the L2 derivative of the corresponding L2 differentiable
parametric family created via the call in the slot CallL2Fam.
Objects can be created by calls of the form new("ContIC", ...).
More frequently they are created via the generating function
ContIC, respectively via the method generateIC.
CallL2Fam:"call":
creates an object of the underlying L2-differentiable
parametric family. name:"character" Curve:"EuclRandVarList"Risks:"list":
list of risks; cf. RiskType-class. Infos:"matrix"
with two columns named method and message:
additional informations. clip:"numeric":

standardizing matrix. lowerCase:"OptionalNumeric":
optional constant for lower case solution. neighborRadius:"numeric":
radius of the corresponding (unconditional) contamination
neighborhood.
