Stata
This site offers a wealth of information to existing and
potential Stata users. It includes extensive information on their
products, and equally extensive user support. The latter includes
FAQs, archives of their mailing list (described here in the mailing
list section), copies of the Stata Technical Bulletin diskette (not
the STB Journal), which includes bug fixes, user written programs,
and new features. In a nice innovation, they even offer courses over
the Internet. They even offer links to other providers of
statistical software.
