How can mathematics predict March Madness?
To figure out the number of possible ways for the tournament to progress, you multiply 2 by itself 67 times to provide the number of different ways to fill out the tournament bracket. The number 2, when multiplied by itself, grows into a very large number after just a few times.

What are the odds of a perfect March Madness bracket?
They are almost definitely exaggerating another fishing story. The odds of making a perfect March Madness bracket are nearly one in 100 billion. So if everyone on the planet filled out a different bracket, we would almost certainly still not have a perfect one. To put it another way: if you play the lottery, you really do not count on winning.
Has anyone correctly predicted March Madness?

Predicting March Madness with Logistic Regression
Every year after the tournament teams are announced on Selection Sunday, millions of people fill out brackets and try to predict the next Cinderella story. Everyone has their own strategy; whether it involves picking your favorite player or the best mascot, but below we’ll review how to use data to find value across the sports betting market.
The Model
A logistic regression model allows us to use input variables to make a prediction on whether or not a binary (yes / no) event will occur. The model uses only the specified input variables to make a prediction without taking anything else into consideration.
How to Use it
If you used the model to predict the outcome of every game this year, you would have correctly predicted the winner in 76% of all games. The model also has a log loss under 10%, meaning that it performs better in predictions with a higher degree of confidence.
Power Rankings
We can also use the model for some more detailed analysis beyond head to head match-ups. The model makes a prediction for every possible match-up regardless of where teams are located on the bracket. Since there are 68 teams in the tournament, the model will generate a predicted probability of winning against all 67 competitors.
What information does Elo use to adjust a team’s rating?
The information that Elo relies on to adjust a team’s rating after every game is relatively simple — including the final score and the location of the game. (As we noted earlier, college basketball teams perform significantly worse when they travel a long distance to play a game.)
Is a 30-35 game regular season a large sample?
The reason is that a 30- to 35-game regular season isn’t all that large a sample. Preseason rankings provide some estimate of each team’s underlying player and coaching talent. It’s a subjective estimate, but it nevertheless adds some value, based on our research.
What is March Madness?
Each March, the National Collegiate Athletic Association (NCAA) conducts a popular college sporting event known as March Madness, a single-elimination tournament to select the national championship from 68 college basketball seeded teams [1]. One of the best parts of March Madness tournament is not only watching the great competitions, but also following the excitement of participating in a bracket challenge to predict the outcome of the tournament games. In 2016, tens of millions of bracket predictions have been created and submitted to bracket challenge contests organized by the companies and associations, for instances, NCAA [2], Kaggle [3], ESPN [4], Yahoo [5], and NBC [6].
What is matrix completion?
Matrix completion is the process of recovering the unknownentries of an incomplete matrix based on a small set of observed samples [15, 16, 17]. In our model, we apply the Singular Value Thresholding (SVT) algorithm [18], one of the popular matrix completion approaches, to complete each perturbed score matrix. In theory, the SVT algorithm seeks a low-rank matrix that minimizes the following Lagrange dual function,
When was the March Madness Kaggle competition cancelled?
As mentioned previously and shown below, our model won a solo silver medal at the NCAAW March Madness Kaggle Competition in 2019 and 2021 (the 2020 tournament was cancelled due to COVID-19).
Is a 3rd seed in the Sweet 16?
However, a 3rd seed is not expected to make the final four. A chalk model (a model that simply assumes the stronger seed wins) will expect a 3rd seed to get beaten by a 2nd seed in the sweet 16 and expect only 1st seeds to remain in the final four.
March Madness Predictions using PyMC3
This post describes my journey from exploring the model from Predicting March Madness Winners with Bayesian Statistics in PYMC3! by Barnes Analytics to developing a much simpler linear model.
The First Model (Off. and Def. Score Decomposition)
As mentioned in the beginning of the post, this model is heavily based on the post by Barnes Analytics. The model seems to originate from the work of Baio and Blangiardo (in predicting footbal/soccer results), and implemented by Daniel Weitzenfeld.
The Second Model (Single Score per Team)
One of my favorite things to do is to take a problem and try to find the simplest model that can solve the problem to a reasonable degree. For this prediction problem, I want to assign only one score per team, use the difference of the scores between two teams to predict the difference of their final points in a game.
Concluding Remarks
Surprisingly, the second model performs better than the first model. In additional to the 2%+ improvement in accuracy, the better logloss values also indicate a better quality in probability predictions.
