plot.h.mlcv: Plot for Maximum-Likelihood Cross-validation

In kedd: Kernel Estimator and Bandwidth Selection for Density and Its Derivatives

Description

The plot.h.mlcv function loops through calls to the h.mlcv function. Plot for maximum-likelihood cross-validation function for 1-dimensional data.

Usage

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

Arguments

x	object of class h.mlcv (output from h.mlcv).
seq.bws	the sequence of bandwidths in which to compute the maximum- likelihood 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 maximum-likelihood cross-validation function are sent to graphics window.

kernel	name of kernel to use.
seq.bws	the sequence of bandwidths.
mlcv	the values of the maximum-likelihood cross-validation function in the bandwidths grid.
