2014 NCAA Men's Division 1 Basketball Tournament Prediction Accuracy

 

Nate Silver's relaunch of FiveThirtyEight.com includes predictions for the 2014 NCAA Men's Division 1 basketball tournament. Nate's model provides the odds of each team advancing in the tournament and is updated after each game.

We use Brier scores to determine the accuracy of the probabilistic predictions in Nate's model.

How did Nate's model perform?

Through the 67 games played in the tournament, Nate's model has a Brier score of 0.2096.

Assigning each team a 50% probability of winning would produce a Brier score of 0.25. Nate's model performed 8% better than assigning each team a 50% win probability, making it a low-skill model for the tournament.

Details of what that means and results for all 67 games are here.
