I was checking out the BPM stats on Rodman, and they don't capture his impact at all. Not even defensively.

Anyone have a clue as to why this is?

Thanks for doing all the scoring Mike. I'm just happy I beat Vegas.

Is the winner of this contest to be judged by MAE or RMSE?

Seems I'm off to a hot start. Let's see how long I can hold pole position.

I've heard that he's really good at denying his man getting the ball, and some other things we don't really think of when grading defensive bigs. We tend to focus solely on rim protection.

Anyone want to give those of us without ESPN+ the top 25 or so.?

Here are mine: Warriors 64 Raptors 57 Jazz 56 Rockets 55 Celtics 54 Sixers 52 Thunder 51 Nuggets 50 Bucks 49 Lakers 46 Wizards 45 T-Wolves 44 Pelicans 44 Pacers 44 Heat 43 Spurs 41 Blazers 40 Hornets 39 Pistons 37 Clippers 36 Nets 36 Grizzlies 33 Mavericks 32 Cavaliers 32 Magic 27 Knicks 25 Hawks 25...

This Topic has been split off from http://www.apbr.org/metrics/viewtopic.php?f=2&t=9517 I am working with a 20 year RAPM dataset (1997-2017) to develop a new BPM formulation. With a pure linear statistical plus minus, here are the residuals: https://docs.google.com/spreadsheets/d/1IcYySAnIZNhSA...

Back in grad school, I had access to SPSS, which I found phenomenal. Now that I no longer have access to SPSS, I spent some time learning R, and I've begun learning Python.

What do you guys use? Which do you find the best?

It seems like the Luka Doncic comparisons and low rating (from 538) are based simply on biographical data:

"This year, we’ve introduced simple projections for European draftees based on biographical data: specifically, their age, draft position, height, weight, position "

Great explanation DSMok. Thank you.

From the About BPM page: "Assist% is a linear term, but assists also figure in both of the interaction terms in the regression, so the specific coefficient for this linear term has no meaning by itself." Yea I guess I'm just not understanding how it has no meaning by itself if it is inclu...

Hey I have some questions regarding how BPM is calculated, using John Stockton as an example. 1. Looking at basketball-reference's explanation of BPM, the coefficient value for assist % is negative. Does this mean Stockton gets docked for having a high assist percentage? Or am I reading that wrong? ...

Butler finished 10th in the regular season and 17th when including playoffs.

Thanks Shadow. Do you plan on doing a prior informed version as well?
