It was fixed in Statistics::Contingency 0.08. IMHO AI::Categorizer should depend on this version, not 0.06. -- Alexandr Ciornii,

Thanks Alexandr. I haven't been able to keep up with my CPAN modules lately and I would very much welcome it if you're interested in maintaining it, or even just doing a release with some of the known problems. Let me know & I can grant you maintainer status on PAUSE and on the SVN repo. -Ken
