TITLE(dof @@ Compute degrees of freedom (wavelet) )
Compute degrees of freedom for wavelet thresholding model
USAGE(
dof(wd)
)
ARGUMENTS(
ARG(wd@@)
The wavelet object
)
PARA BOLD(VALUE)
The number of degrees of freedom.
The wavelet thresholding is a non-linear transform and dof returns
the approximate number of degrees of freedom.

EXAMPLES(
#
# Do a wavelet decomposition of noisy data
#
> ywd <- wd(ynoise)
#
# Threshold
#
> threshy <- threshold(ywd)
#
# Compare degrees of freedom
#
> dof(ywd)
[1] 512
> dof(threshy)
[1] 11
