Here is the 2015 bracket:
What was the Data and How was it Analyzed?
The Data Viz and Predictive Analytics team pulled publically available data from multiple sources including: ESPN.com, Wikipedia & GPS Visualizer. The key statistics include: College Basketball Power Index (BPI), Strength of Schedule, Conference Rank, Win/Loss in the last 12 games and Net Points vs. Average. Each individual match-up was compared and analyzed on a team-by-team basis.
SAP Predictive Analytics determines significant measures making the most contribution to our predictive model. Of all 351 Division 1 basketball teams, we isolate the 68 tournament teams for a robust analysis.
Looking at initial results, we see that Average Scoring Margin and Strength of Schedule together make up more than 25% of our model.
Next, we isolate the variables that gives us more than 90% model certainty.
We use the KxIndex results to rank and choose our teams in our bracket. Several matchups however are too close to confidently pick so we are deep diving with additional analysis.
Offensive / Defensive Performance and Scoring Margin
Looking at scoring margin (net points vs. average) and offensive / defensive performance (quotient) we can better understand a team’s playing style, its effectiveness, and how they win. Notre Dame, for example, rely mainly in their scoring ability while a team like Wichita State is a stronger defensive team.
Quality of Wins & Losses vs. Quality Opponents
How do teams play against quality opponents? Quality wins against tough opponents can be a great predictor. While Kentucky has gone unbeaten this year it has only played 5 games against top-25 ranked teams. Kansas is seemingly battle-tested having played 14 top-25 ranked opponents and winning 9 games.
Recent Wins, Winning Streak & Quality Wins
We are also watching hot teams streaking into the tournament. Lower ranked teams like Stephen F. Austin are particularly dangerous since they’ve had to win their conference tournaments to qualify.
Tournament Teams by School Location
Traditional powerhouse conferences like SEC and ACC are well represented this year. Mid-west teams are strong, with 7 teams (Michigan State, Wisconsin, Purdue, Indiana, etc.) from the Big Ten.
We then turned to SAP Predictive Analytics to crunch through the data. Building a cluster analysis to get an idea of how the teams split out based on their rankings:
Then we looked at each cluster by strengths and weaknesses.
The team then built a Decision Tree on the variables to get an idea if this lined up with the Cluster break out found in the first 2 steps while using variables from the regression analysis:
