plot.h.tcv: Plot for Trimmed Cross-Validation

Description

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

Usage

## S3 method for class 'h.tcv':
plot(x, seq.bws=NULL, \dots)
## S3 method for class 'h.tcv':
lines(x,seq.bws=NULL, \dots)

Arguments

x

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

seq.bws

the sequence of bandwidths in which to compute the trimmed 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 trimmed 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.
• tcv
  the values of the trimmed cross-validation function in the bandwidths grid.
