[edit] realtimerpi

I have removed realtimerpi from the external links section *repeatedly* because it is unnecessary with the official NCAA RPI above it.

The RPI calculation is so simple (I can almost do it in my head) that there are many sites on the Internet that have the RPI available in realtime: this in itself is non-notable. You may know of some media outlets that quote their data, but I have seen articles that quote the RPI of each of kenpom.com, warrennolan.com, boydsworld.com, collegerpi.com, espn.com, rpiratings.com and teamrankings.com. As such, being quoted by the media is also non-notable.

You may have an affection for this site (or a commision from it), but if wikipedia needs a link to realtimerpi, then it should have links to all the rest of the sites that provide this commodity service, and that would be over the top for a 2 1/2 paragraph article.

  • I disagree with your removal. The NCAA's RPI numbers are only updated weekly, and it may be useful to our readers to have a source which updates daily (or more frequently) such as RealTimeRPI or Ken Pomeroy's site. Either of these is frequently cited in mainstream media. I personally favor Pomeroy's site as it has fewer ads, but I think it is not out of place to have one of those links.

OK, then we will go with Pomeroy then. I am agnostic as to the site but it should be free (which rules out Jerry Palm's CollegeRPI) and cited in mainstream media. I would prefer if the site was a mainstream auto-updated site but ESPN and the like charge for their real time versions. By the way it helps your credibility greatly if you register for a user name.

[edit] Wow, RPI can also be used for ranking any leaders, can it? hoh hoh.....

look forward to seeing the applicaion in other fields —The preceding unsigned comment was added by 72.52.66.10 (talk) 06:18, 18 March 2007 (UTC).

But, but is it a validated method?....I mean if it is validated by sets of training and validation data, or by another relevant method?

If the article can not provide any scientific references on the method validation, please indicate it somewhere in the article. Otherwise, it is misleading the public. I have seen an article abstract at

http://www.bepress.com/jqas/vol2/iss3/3/

However, I'm not sure what the ranking results are using RPI and OLRE. If the ranking results are consistent with each other by these two methods, then RPI is a validated method. Any people who is able to access to the journal article, please add some relevant info to the front article
