wavethresh (version 4.6.1)

denwd: 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

Value

• An object of class wd.object

Details

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

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)
plotdenwd(data.wd, top.level=(datahr$res$J-1))
