| CondContIC-class {ROptRegTS} | R Documentation |
Class of conditionally centered (partial) influence curves of contamination type for conditional contamination neighborhoods; i.e., influence curves eta of the form
eta = (A Lambda - a)min(1, b/|A Lambda - a|)
with clipping function b, centering function a and
standardizing matrix A. Lambda stands for
the L2 derivative of the corresponding L2 differentiable
regression type family created via the call in the slot CallL2Fam.
Objects can be created by calls of the form new("CondContIC", ...).
More frequently they are created via the generating function
CondContIC, respectively via the method generateIC.
