The package implements a variety of tools for categorization of multivariate data such as boosted decision trees, bagging and random forest, bump hunting (PRIM), a multi-class learner and others.

I've been once more prodded into activity by Ilya, and so the SPR source repository is once again active on SourceForge. After my poll of preferred VCS systems, I decided that it was best to stick with the centralised version control that we know and love, so the repository is now using Subversion (sort of "CVS++", if you're unfamiliar: most cvs commands will continue to work, with the "cvs" command itself exchanged for "svn"). I encourage wannabe contributors to use Bazaar (http://bazaar-vcs.org) to use the bzr-svn plugin to make versioned patches and send them to me, thus avoiding the problem of needing lots of people to have commit access to the main repository. I've also taken the opportunity to update the http://statpatrec.sf.net web page, now composed of HTML built from an updated version of the README file via asciidoc (http://www.methods.co.nz/asciidoc/). Comments and improvements are very welcome!
I've just pushed up a new release of SPR, which does the ROOT detection / absence-handling better, and also uses Ilya's preferred compilation flags (using ROOT will downgrade the optimisation level somewhat). Sorry to those who know that I've basically had this version ready for release for about 2 months and haven't had the time/energy to do the final push online. Oops. On that note, I'd like again to appeal for anyone who's actively using the package to consider becoming a maintainer... while I hope to get more active again in future, it's been a very non-SPR year for me! And now a little advert for an SPR helper tool by Piti Ongmongkolkul: > I have written a tool to visualize decision trees. It can be found here: > http://www.slac.stanford.edu/~piti/treemaker/ > > See output sample here: > http://www.slac.stanford.edu/~piti/treemaker/screenshot.pdf
2009-05-28 Andy Buckley <andy@insectnation.org> * 3.3.2 release. * One more ROOT-handling fix: finish configure gracefully if ROOT can't be found. 2009-03-30 Andy Buckley <andy@insectnation.org> * Build system fixes: handle case where ROOT is not present better, remove build flag duplication, proper propagation of CXXFLAGS variable for changing optimisation and debug mode.
