I took some time to revise the Website Analytics article. The data that I originally posted had some errors which have now been corrected. I've also taken the suggestion of CSandB and used Pearson's correlation coefficient to calculate the actual relationships between the external metrics and the stats data:

1. Number of Technorati Links (0.74)
2. SEOmoz Page Strength (0.60)
3. Number of Links to the Blog URL via Yahoo! Site Explorer (0.56)
4. Number of Links to the Domain via Yahoo! Site Explorer (0.54)
5. Bloglines Subscriptions (0.49)
6. Technorati Rank (0.49)
7. Alexa Rank (0.49)
8. Netcraft Rank (0.43)
9. Newsgator Subscribers (0.39)
10. Compete.com Rank (0.38)
11. Ranking.com Rank (0.36)
12. Google PageRank (0.21)

Technorati links is actually an almost usable option at this point though any scientific analysis would tell you that correlations below 90-95% shouldn't be used. We're also thinking about new ways to use this methodology to build and improve on some of our tools (Page Strength for one).

If you've got some other great ideas of how to use this data please let us know - I'll be more than happy to link out to anyone who can use this information in new and fascinating ways. In case you're interested the Excel file is downloadable here.

Update: I've made some changes to the Excel file and the article based on some additional inputs from the contributors.
