rlsOptIC.AnMad | R Documentation |
The function rlsOptIC.AnMad
computes the optimally robust IC for
AnMad estimators in case of normal location with unknown scale and
(convex) contamination neighborhoods. These estimators were
considered in Andrews et al. (1972). A definition of these estimators
can also be found in Subsection 8.5.3 of Kohl (2005).
rlsOptIC.AnMad(r, aUp = 2.5, delta = 1e-06)
r |
non-negative real: neighborhood radius. |
aUp |
positive real: the upper end point of the interval to be searched for a. |
delta |
the desired accuracy (convergence tolerance). |
The optimal value of the tuning constant a can be read off
from the slot Infos
of the resulting IC.
