# Spatio-Temporal Nonparametric Distributional Analysis of NBA Defenses: Introduction and Teaser

Back in 2012, on the heels of my PhD in nonparametric Bayesian density estimation, I developed a methodology that constructs a nonparametric Bayesian density and teases out a nice spatio-temporal decomposition of movement on a space of interest. Pointing this at NBA SportVu data, the decomposition kindly identified player tendency in specific types of offenses…

# NBA Finals: Review of the MCMC

Now that the Finals are upon us (finally!), let’s take a look back at the Markov Chain simulator that we built for this post-season, evaluate how we did, and take a look at the NBA Finals!   Round 1… 7 for 8 There were no surprises in the first round of the NBA Playoffs. In…

# Identifying Player Possession in Spatio-Temporal Data

In a previous post, we took a look into some spatio-temporal data obtained through SportVU technology for the NBA and identified how to use that data to perform basic tasks such as building convex hulls to illustrate offense and defense coverage on a court; as well as provide basic Python code for the reader to…

# Markov Simulation: NBA Playoffs Round 2

In continuation of our Markov simulation of the NBA Playoffs, we take a look at the updated probabilities for each team remaining. In this article, we take a cursory look at each second round match up and see how the first round panned out compared to the probabilistic predictions. So Far So Good: All rounds…

# Markov Simulation: NBA Playoffs

With the NBA Playoffs set to get underway, we take a quick look at the probabilities for each team becoming the NBA Champions. Common consensus would place any combination of the five strongest teams: Golden State – Houston – San Antonio versus Cleveland – Boston. But the question is how likely? To answer that, we…

# NBA Predictions for 2016-2017

Only a few days delayed due to an impromptu trip to Ottawa and a swing through Sacramento to catch the Kings upend the Minnesota Timberwolves 106-103 last night, my pre-season predictions are finally available for your viewing pleasure. In this edition, we take a look at the rosters on opening day and compute their expected…

# NBA Power Rankings – November 15th Edition

Over the course of the past week, there have been another 58 NBA games that have been played, bringing the total number of games played to 151; over ten percent (12.28%) of the season complete. To date, we still have one undefeated team (Golden State, 11-0) and one winless team (Philadelphia, 0-10). Using the beta…

# NBA Possessions: Rewards System

With the 2015-16 NBA regular season slated to open on October 27th, just a mere ten days away, we figured to take a look at possession data from seasons past. An NBA possession is effectively the time that an offense gains possession of the basketball until the time the ceases to maintain possesion. There are…
