Hi all, On a request from a colleague, I programmed an implementation of the clinical significance estimation suggested by Jacobson and Truax some years ago, with a few generalizations and a couple of plot functions. I have wrapped this up in a package, but I am reluctant to further clutter CRAN with a package containing one function with print and plot methods. If anyone out there would like to include this function in a suitable package, please let me know. Jim Jacobson, N.S. & Truax, P.
