Plots the Approximate R-Square for the Different Splits
DESCRIPTION:
Produces 2 plots.
The first plots the r-square
(apparent and apparent - from cross-validation)
versus the number of splits.
The second plots the Relative Error(cross-validation) +/- 1-SE from
cross-validation versus the number of splits.
USAGE:
rsq.arbor(x)
REQUIRED ARGUMENTS:
- x
-
fitted model object of class
arbor
. This is assumed to be the result
of some function that produces an object with the same named
components as that returned by the
arbor
function.
SIDE EFFECTS:
Two plots are produced.
NOTE:
The labels are only appropriate for the
"anova"
method.
EXAMPLES:
z.auto <- arbor(Mileage ~ Weight, car.test.frame)
rsq.arbor(z.auto)
