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)

REQUIRED ARGUMENTS

coef
Output from denproj.

VALUE

An object of class wd.

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))
