A peek into how just about every analytics ranking system is biased by preseason ratings

Should be a real challenge this weekend. Go Cougs!

Awesome. UW is 2-1 w a neutral field loss to Wazzu. Wazzu is 3-0 w a neutral

It is super lame. At least now as BYU fans instead of complaining about P4 bias,

Which of course, makes sense. A ranking system based entirely on 1 or 2 or even 3 games would be completely worthless.

Yeah and no - UW beat Weber State and Eastern Mich by middling margins. Then

No way. It’s a statistical model, it will never be perfect. But calling out examples like that is pointless

TCuz

A "statistical model" that doesn't factor a head-to-head loss and a far more

oxcoug

You are missing the point. Of course it factors in the head to head loss, just not as much as you want it to.

Baseball has the luxury of a ton more games to put into the model. College

TCuz, you're usually good at arguments, but bringing up baseball (with its

Sep 16, 8:34am

It’s a great example (not perfect). Because essentially what you are doing is saying hey, the Padres beat the Dodgers

TCuz

The better example is UTEP's only win was BYU's only loss. No one, not a UTEP

NYC and Japan

Sep 16, 11:09am

Mm. That UTEP team went 1-10. Wazzu's 3-0 w bigger margins vs better competition

It would be limited, but this model is *worse* than worthless, because it creates capricious bias based on something

The weaker the signal, the more weight you put on your prior. That isn't bias.

rankings would be a laughing stock if they didn't do this however

Hill4Heisman

Sep 16, 10:47am

It would be better for them to look meaningless until they have actual meaning.

mvtoro

Or ideally, they could figure out how much to weight preseason priors, using historical data to get the best predictions

krindorr

Sep 16, 11:18am

Statistically/analytically this makes sense though; historically a better predictor than just overreacting to game or 2

krindorr

Sep 16, 11:13am

What makes the most sense is to not rank teams until at least part way in.
