plot.h.ucv {kedd}

Plot for Unbiased Cross-Validation

Description

The plot.h.ucv function loops through calls to the h.ucv function. Plot for unbiased cross-validation function for 1-dimensional data.

Usage

## S3 method for class 'h.ucv'
plot(x, seq.bws=NULL, ...)
## S3 method for class 'h.ucv'
lines(x,seq.bws=NULL, ...)

Arguments

x

object of class h.ucv (output from h.ucv).

seq.bws

the sequence of bandwidths in which to compute the unbiased cross-validation function. By default, the procedure defines a sequence of 50 points, from 0.15*hos to 2*hos (Over-smoothing).

...

other graphics parameters, see par in package "graphics".

Value

Plot of 1-d unbiased cross-validation function are sent to graphics window.

kernel

name of kernel to use.

deriv.order

the derivative order to use.

seq.bws

the sequence of bandwidths.

ucv

the values of the unbiased cross-validation function in the bandwidths grid.
