estimate.sdev: Estimate noise level from wavelet coefficients

Description

estimate.sdev estimates by analysing the the wavelet coefficients at the finest level(s) of an wd or imwd object.

Usage

# S3 method for wd
estimate.sdev(object, dev=mad)
# S3 method for imwd
estimate.sdev(object, dev=mad)

Arguments

object

For extract.coefficients the wd or imwd object for which to estimate the standard error.

dev

The function used to estimate the standard error. Typical examples are sd, or the more robust mad (default).

...

additional arguments (see above for supported arguments).

Value

estimate.sdev returns an estimate of the standard error.
