| TotalVarIC-class {ROptEstOld} | R Documentation |
Class of (partial) influence curves of total variation type. i.e., an influence curves eta of the form
eta = max(c, min(A Lambda, d))
with lower clipping bound c, upper clipping bound d and
standardizing matrix A. Lambda stands for
the L2 derivative of the corresponding L2 differentiable
parametric family which can be created via CallL2Fam.
Objects can be created by calls of the form new("TotalVarIC", ...).
More frequently they are created via the generating function
TotalVarIC, 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. clipLo:"numeric":
lower clipping bound. clipUp:"numeric":
upper clipping bound. stand:"matrix":
standardizing matrix. neighborRadius:"numeric":
radius of the corresponding (unconditional) contamination
neighborhood.
Class "IC", directly.
