Dear Ken,

in addition to what Saji suggested, you could use the statistics2 package 

http://raa.ruby-lang.org/project/statistics2/

which is a statistics library in pure Ruby, or, if you want extremely exhaustive
statistics, there are bindings to the very encyclopedic R statistical language.

http://www.r-project.org/
http://rubyforge.org/projects/rsruby/

I haven't been able to use the latter bindings with Windows, though.

Best regards,

Axel
