RE: 538 Sports Bracket Interacive Predictions
For my man Stammers:
'The model, which is in its fourth year, is principally based on a composite of five computer power ratings:
■Ken Pomeroy’s ratings
■Jeff Sagarin’s “predictor” ratings
■Sonny Moore’s ratings
■Joel Sokol’s LRMC ratings
■ESPN’s Basketball Power Index, a new addition this year
Each of these ratings has a strong track record in picking tournament games. We shouldn’t make too much of the differences among them: They are all based on the same basic information (wins and losses, strength of schedule, margin of victory) computed in slightly different ways (for example, the Moore ratings place a lot of emphasis on recent performance whereas the other systems do not). However, the reason to use five systems instead of one is because even small differences can compound over the course of a tournament that requires six or seven games to win. For instance, a team that is an 80 percent favorite to win each of its games has a 26 percent chance of going on a six-game winning streak, whereas one with a 70 percent chance has only a 12 percent chance of doing so. Each system has different features and bugs, and blending them helps to smooth out any rough edges."
and
"RPI is the Dick Morris of algorithms. Maybe I should challenge it to a bet."
Most people already knew this, though. Just reaffirming to hear a real stat guy (with a track record of success) state it.

RE: 538 Sports Bracket Interacive Predictions
Louisville got a great draw. Probably better to be the 4 in that region than the 1.
I'm still not sold on KY auto-advancing past Kansas St. Kentucky hasn't really beaten anyone of Kansas St's caliber on a neutral / away floor all year, except for possibly Providence. I'm not sure why most people are looking beyond Kansas St in that one.
Each time I look at the brackets, I still think we ended up in just about the best possible spot. If we had to trade with anyone, it would be Louisville.

Ran it 10 times for each. Memphis won 8, GW won 2. UVA and the Tigers split 5 and 5.

I ran it 20 times for Memphis vs Virginia and Memphis won 11, UVA won 9. So the simulation see's it as around a 50/50 game

Memphis wins 110-108 in double overtime for me. Joe with 27 and Shaq with 26 but Nichols and Shaq both foul out. It's a little dumb because it has Crawford shooting 4 free throws.

Interesting that in Mem vs UV 20 times .......Virginia wins are close while Memphis wins are mainly 20 point blowout wins.

RE: 538 Sports Bracket Interacive Predictions
Had some time to kill, so ran the UVA-Mem match 100x. 52-48, Memphis. So according to that simulation, UVA better watch out!
The scores were frankly, all over the place. Some were nail biters both ways, sometimes we won big, sometimes they won big. The only consistent thing that popped out from that oracle, was that if Memphis is ahead at the half they generally win, and if the game goes to OT, they win the larger percentage of those.

Pace/style.
UVA plays it slow. We are at our best quick.

A little dumb is right

What were you wearing? Maybe you should change and try it again.

I believe there are now pedophilia laws on the books that outlaw that attire.

RE: 538 Sports Bracket Interacive Predictions
Looks like it generates Memphis as a 70% favorite.
Kentucky vs Kansas St has Kentucky as a 60% favorite.
Those look like reasonable odds. I'm going to run some others.

RE: 538 Sports Bracket Interacive Predictions
Just ran Arkansas and Kentucky and it was 11-9 in Arkansas' favor. Its a very limited data set, but it at least seems to be generating reasonable expectations.
For fun, I did Memphis '08 vs Kentucky '10. Memphis wins 8-2.
Memphis 08 vs Kentucky 12 was Memphis 7-3. Dang that 08 team was good.
I'm not even going to do Memphis 08 vs Kansas 08.

RE: 538 Sports Bracket Interacive Predictions
538 does a great job of consolidating many sources of polling data for coming up with good election predictions, although I don't think they do any primary research. I've got to think it's a lot harder to come up with accurate predictions for sporting events using the various ranking indices, especially when you have so many teams involved and a limited number of common opponents. Still, good info to look at and I trust 538's opinion more than I do the NCAA selection committee's.
