A paper describing the methods used in Barber & Nason. A preprint version of this paper is available.
The basic WaveThresh3 distribution is a prerequisite for CThresh. You must have WaveThresh3 loaded to be able to run CThresh. WaveThresh3 itself requires R - see the wavethresh web pages for more details.
The following software and help pages were written by Stuart Barber.
The CThresh software can be downloaded here:
gunzip cthresh.tar.gz tar -xvf cthresh.tarOn Windows, an archiving utility like WinZip or EasyZip should be able to extract the necessary files.
Installation is described in the README file in the distribution (note that Windows users will need to be able to compile the C code, sorry). For the empirical Bayes method to work at its fasted, you will need access to the FORTRAN NAG library.
Cthresh has a number of help pages. They are included in the distribution file above, or you can look at them separately:
