R: Wavelet decomposition of empirical scaling function...

denwd {wavethresh} | R Documentation

## Wavelet decomposition of empirical scaling function coefficients of a p.d.f.

### Description

Performs wavelet decomposition on the empirical scaling function coefficients of the probability density function.

### Usage

    denwd(coef)

### Arguments

`coef` | Output from `denproj`

### Details

The empirical scaling function coefficients are decomposed using the DWT with zero boundary conditions.

### Value

An object of class `wd.object`

### Author(s)

David Herrick

### Examples

    # Simulate data from the claw density, find the empirical
    # scaling function coefficients, decompose them and plot
    # the resulting wavelet coefficients

    data <- rclaw(100)
    datahr <- denproj(data, J=8, filter.number=2,family="DaubExPhase")
    data.wd <- denwd(datahr)
    ## Not run: plotdenwd(data.wd, top.level=(datahr$res$J-1))
