Statistics modules in Perl Data Language, with a quick-start guide for non-PDL people. They make the PDL shell work like R, but with PDL threading (fast automatic iteration) of procedures including t-test, linear regression, and k-means clustering.
Good module built on PDL. But live tutorials are meagre. I suggest the developer to prepare a course on open platform like Coursera, edX about this module with real world data analysis like analysis of Framingham Heart Study data. Regards
