lmrobdetMM
fitThis function computes the RFPE for the MM-estimators obtained with lmrobdetMM
by
recomputing it, successively removing each of a number of specified terms.
It is used internally by step.lmrobdetMM
and not meant to be used
directly.
## S3 method for class 'lmrobdetMM'
drop1(object, scope, scale, keep, ...)
object |
the |
scope |
an optional |
scale |
an optional residual scale estimate. If missing the residual
scale estimate in |
keep |
a character vector of names of components that should be saved for each subset model.
Only names from the set |
... |
additional parameters to match generic method |
An anova object consisting of the term labels, the degrees of freedom, and Robust Final
Prediction Errors (RFPE) for each subset model. If keep
is missing, the anova object is
returned. If keep
is present, a list with components "anova"
and "keep"
is returned.
In this case, the "keep"
component is a matrix of mode "list"
, with a column for each
subset model, and a row for each component kept.
