Talk:Sports rating system

Untitled

I have been reading the guidelines and was wondering if I could add a link to the college sport rankings I develop in this article. Please let me know. Thanks (75.48.166.81 (talk) 00:34, 20 April 2008 (UTC))

External links: no linkspam

I removed the following list of links from the External Links section of the article. While some of these may actually have merit, there should be inline references to them in the article with annotation about why they're notable. See WP:EL. I welcome discussion on this topic and think that some of these links will end up being notable. Right now, however, there's a poor mix that doesn't serve the reader.

1. Check out @octonion's Tweet: https://twitter.com/octonion/status/540622289331847168?s=09. He uses distance traveled as well as altitude change to affect home advantage.
2. To describe the difference between algorithms that only describe the past and ones that try to predict the future, see prediction of teams' records at season's end, their likely playoff chance, and likely success through the playoffs. See March Madness predictions, for instance.
3. It would be interesting to write more about confidence in ratings; like reddit / hacker news comes up with scores, see the lower bound of these two:
   1. Binomial proportion confidence interval, though this requires independent tests (draw with replacement)
   2. Hypergeometric distribution if you believe that games are not independent (draw without replacement)

Informal "power rankings" as seen in/on publications/websites such as Sports Illustrated, ESPN, USA Today, Bleacher Report, etc.

This term "power rankings" redirects here. That term typically refers to a informal (generally weekly) ranking of teams in a particular sport based on the opinion of one or more experts/analysts for that sport and intended for the readers of the publication only. These informal power rankings generally include a bit of info as to what the expert/experts think about the teams play over the last week and/or why the ranked the team where they did. Unlike the college football polls, these "power rankings" do not play any roll in whether a team makes the playoffs. We should try and at least provide a short summery of what these informal "power rankings" are. Also, this article needs more info on what ranking systems including informal rankings systems published on websites/sports publications, are used in non-U.S. countries for sports such as association football, rugby, cricket, tennis, hockey, golf, etc. --2600:1700:56A0:4680:11D:A4DF:284A:4E0E (talk) 17:03, 20 August 2018 (UTC)
