Examples of such tests are: --- Kolmogorov-Smirnov test; --- Smirnov-Cramer-von Mises test; --- Anderson-Darling test. Am I right, or these functions are already provided in GSL? If not, as I think, is it planned to have them in future extensions, and if this is the case when more or less? Thanks, Best regards, Alberto Ribon. ^ permalink raw reply [flat|nested] 6+ messages in thread

GSL doesn't have any statistical tests at the moment, since nobody has volunteered to write them. If you'd like to write some let me know.

Central in this project is the employment of different statistical tests, like Chi2, Kolmogorov-Smirnov, Smirnov-Cramer-von Mises, Anderson-Darling, etc... This project will be written in * C++ * and will be * free software *. Furthermore, for the histogram part, we plan to use another C++ free software package, developed in the same High Energy Physics community, called AIDA/Anaphe: http://aida.freehep.org/ http://cern.ch/anaphe/ (another package, still in C++ and free software, which is currently heavily used by all High-Energy Physics community, and which provides lots of useful mathematical functions, is CLHEP: http://cern.ch/clhep/ this is not directly linked with the statistical tests, but I think it is worth to bring it to your attention) We plan to have a first release of it for Spring-Summer 2003. We are quite interested and pleased to provide this code to GSL, including the necessary integration effort with the rest of GSL. We will contact you as soon as we have a working first version. Best Regards, Alberto Ribon PS- I'd like to thank and acknowledge for the replies I received previously (see below), from Ramon Diaz and Jason H. Stover, who pointed me on the GNU R project. I had a look at it, but we don't think it provides what we really need. ------------------------------- On Mon, 9 Dec 2002, Brian Gough wrote: ->Alberto RIBON writes: -> > I am not writing for reporting a bug, but for asking a question: -> > I have looked through the various GSL functions but I haven't -> > found any function related to statistical tests, that is to -> > determine the probability that a distribution (histogram) is -> > coming from a certain distribution (which could be an analytical -> > function, or another histogram).

By the way, we would appreciate any information of guidelines and possible constraints relevant for the integration of code in GSL.
