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)
