CHAPTER 6: "A HAAR-FISZ ALGORITHM FOR POISSON INTENSITY ESTIMATION"

The functions have been written in S and designed for S-Plus 2000. Additionally, some of the functions require WaveThresh3, a free add-on module for S-Plus written by Guy P. Nason.

Downloading and installing the functions and the data set.

  1. Click here to download the archive "piefisz.zip", which contains the functions and the data set.
  2. Extract the archive. You will get the file "piefisz".
  3. Run S-Plus and type (in Windows)"data.restore("D:\\PATH\\piefisz")", where D:\PATH is the directory containing "piefisz".
  4. The functions and the data set are now available.
