NBA Final Regular Season Bayesian Ratings

April 15, 2011
By

There is a !  I’m putting together an NBA Playoffs preview; this is the first of the data for that: Here is a table of playoff bound teams and their season-long adjusted efficiency ratings. Ratings are adjusted for location, pace (obviously, since these are per 100 possessions), opponent (recursively) and rest day situation. Previous...

Bayesian Update

It is fairly easy to construct a retrospective efficiency rating. Take the efficiencies for each game, correct for location and rest, and then solve using an OLS regression for each team’s true efficiency rating. Nice and neat. However, how should a predictive rating work? The best approach would be to adjust for what players...

NBA Adjusted Efficiency Rankings 2-6-2011

It’s been a while since I last put together the fully adjusted NBA efficiency rankings. Here are the latest ratings (prev is 1-13-2011, the last time I updated): If you will recall, I last time was puzzling over what exponent to use when minimizing |residuals|^n. I tried out a number of different exponents in...

Center Comparison Chart (and K-Means Clustering)

Last week, I unveiled a Google Motion Chart that included a large number of advanced stats comparing point guards. This week, we'll start at the other end: centers. I actually am including players classified as either C or PF/C by BasketballValue, where I got the position information. Most people feel that the position...

Last week, I unveiled my . This week, I’ll explore some of the decisions I made with that system, per the request of . The first question is how much the ranking are effected by using rest-days adjustments.  See my original research on APBRmetrics for where this comes from.  Here’s a table comparing the...

Point Guard Comparison Chart

By

So, what else can Google Motion Charts be used to visualize? Well, this application doesn’t actually *move*, but it does visualize a ton of point guard advanced statistics at once. That’s quite a few advanced stats in one place!  Play around with the chart and see what can be revealed.  I have 4 player...

Last week, I unveiled the first iteration of my . This week, I’ll revise and expand on it. The main thing I didn’t like about the chart was the 5-game moving averages. The games dropping off the far end of the moving average add just as much movement as the newest game adds. The...
