plot-KernelWeight {quantspec}

Plot the values of the KernelWeight.

Description

Creates a plot visualizing the weights W_n(\omega) [cf. KernelWeight-class] that are used to estimate the quantile spectral density.

Usage

## S4 method for signature 'KernelWeight,missing'
plot(
  x,
  y,
  ylab = expression(W[n](omega)),
  xlab = expression(omega),
  main = x@descr,
  ...
)

Arguments

x

The KernelWeight to plot.

y

missing arg from the generic; will be ignored.

ylab

label for the y-axis; optional

xlab

label for the x-axis; optional

main

titel (on top) of the plot; optional

...

optional parameters used for plotting

Details

In the plot the values at the frequencies 2\pi j / N, j=L+1-N,\ldots,L, L:=\lfloor N/2 \rfloor are shown, where N is the parameter specified on construction of the object or N := 3, if that parameter was smaller than three. A warning is given in the later case.

Value

Plots the KernelWeight.

Examples

plot(kernelWeight(W1, bw=0.3),
       ylab=expression(W[n](x)),
       xlab=expression(x),
       main="Weights to an Epanechnikov kernel", sub="bw=0.3")
