estimate.sdev
estimates by analysing the the wavelet coefficients
at the finest level(s) of an wd
or
imwd
object.
estimate.sdev(object, dev=mad) estimate.sdev.wd(object, dev=mad) estimate.sdev.imwd(object, dev=mad)
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). |
estimate.sdev
returns an estimate of the standard error.
estimate.dev.wd
and estimate.dev.imwd
should rarely be directly called by the user. The more user-friendly S3 function
estimate.dev
will take care of calling the right function.
