PT-PM numbers for 2015-2016

I am belatedly getting around to releasing the final Player Tracking Plus Minus (PT-PM) numbers for 2015-2016. PT-PM is my version of a statistical plus minus model, that I have developed over the last few years.

I wanted to have a place to reference the numbers for future posts and put them out there for anyone interested. First a quick visualization, that pits the Defensive PT-PM against the Offensive PT-PM, with the color representing the overall score and the size of each player's marker determined by the number of minutes he played over the season. The visualization is filitered for players with at least 300 minutes. Plus I think it looks kinda cool.

 

Finally, here's the table with the O and D PT-PM numbers as well as the total score adjusted for playing time (lower minutes players are regressed more). Table can be filtered by team or minutes played.

 

 

Rookie Projections Visualization

This rookie projection visualization, was originally posted on Nylon Calculus. But the dimensions on the host site aren't quite optimized for Tableau visualizations, or at least not the dimensions I am using, so I am giving it a try here to see if it's a bit more readable:

 

 

The basic explanation is at the Nylon post, but in short I tried to highlight a couple of different inputs to the model for projecting end of the rookie contract production from last year's rookies, age, efficiency, time on the court and pre-NBA efficiency.
