estimate.sdev: Estimate noise level from wavelet coefficients

In treethresh: Methods for Tree-Based Local Adaptive Thresholding

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

Note

For an example of the use of estimate.sdev, see coefficients.
