Usage
oneStepEstimator(x, IC, start = NULL,
useLast = getRobAStBaseOption("kStepUseLast"),
withUpdateInKer = getRobAStBaseOption("withUpdateInKer"),
IC.UpdateInKer = getRobAStBaseOption("IC.UpdateInKer"),
na.rm = TRUE, startArgList = NULL, ...)Arguments
IC
object of class "InfluenceCurve"
start
initial estimate (for full parameter,i.e. in dimension $k$ respective
joint length of main and nuisance part of the parameter):
either a numerical value, or an object of class "Estimate" or
a function producing either a numerical
useLast
which parameter estimate (initial estimate or
one-step estimate) shall be used to fill the slots pIC,
asvar and asbias of the return value.
withUpdateInKer
if there is a non-trivial trafo in the model with matrix $D$, shall
the parameter be updated on ${\rm ker}(D)$?
IC.UpdateInKer
if there is a non-trivial trafo in the model with matrix $D$,
the IC to be used for this; if NULL the result of getboundedIC(L2Fam,D) is taken;
this IC will then be projected onto ${\rm ker}(D)$.
na.rm
logical: if TRUE, the estimator is evaluated at complete.cases(x).
startArgList
a list of arguments to be given to argument start if the latter
is a function; this list by default already starts with two unnamed items,
the sample x, and the model eval(CallL2Fam(IC)); in case IC
