I did some googling before making this thread and I was surprised I couldn't find one.

you probably can't find one because it depends on the team stats and league average stats. There are sites that have the up to date numbers updated nightly, but only the full season numbers.

Surprised there is nothing out for this, even a small web app. Is PER patented?

I made an attempt at one in Excel a few years back, but I'm off to work now. I'll see if I can find it later.

Probably no one bothers making one since Hollinger jiggers the system every once in awhile if they don't match up with what he thinks is right.

i've got the formula entered etc. but the only thing i'm not sure about is how to calculate stats for the league average player

dunno whether to just divide season totals of a given stat by the number of games played times 13 (players on the roster) or to use a subtler methodology

https://docs.google.com/spreadsheet/ccc ... jV1E#gid=0

it works reasonably well, lebron's per is 35, durant's is 28, wade's is 29, westbrook's is 24 etc. just enter numbers from bbref in the second column

you guys can edit it so lol let's see how long it lasts

You don't really need to make it that complicated. I ran a regression of the data from 2004/05 to 2011/12 on the basketball-reference.com PER numbers, that's what it boils down to:

PER = 3301.2*(3.498*FGM-1.097*FGA+1.412*3PM+1.861*FTM-0.538*FTA+1.062*ORB+0.422*DRB+0.968*AST+1.559*STL+1.062*BLK-1.529*TO-0.479*PF)/(Pace*Min)

That gives a RMSE of 0.3. So, the league average isn't that big of a deal. For this season for example, multiplying the result with 1.044 gives a RMSE of 0.1.

Pace can be easily calculate using team data: Pace=FGA+0.4*FTA+TO-ORB, that is a good enough estimate.

If you want to calculate PER on a game-to-game basis, you can devide 106.8 by the average ORtg for both teams and use that as a multiplier. That exercise for example, gives us for the Utah vs. Dallas games:

Code: Select all

Utah                  PER
Al Jefferson          8.4
Paul Millsap          38.9
Devin Harris          3.6
Josh Howard           10.4
Gordon Hayward        3.7
Alec Burks            0.6
C.J. Miles            14.0
Earl Watson           7.2
Derrick Favors        34.6
Enes Kanter           5.1

Dallas                PER
Shawn Marion          12.4
Brendan Haywood       9.6
Dirk Nowitzki         48.4
Vince Carter          14.0
Jason Kidd            11.8
Jason Terry           22.3
Rodrigue Beaubois     -0.2
Lamar Odom            33.1
Ian Mahinmi           3.0
Yi Jianlian           0.0

I uploaded the spread sheet I did back in 2007 here:

Link

The sheet was made using basketball-reference.com´s formulas back in 2007. I don´t know if there have been significant revisions during the past 5 years, but Kobe's PER from 2005-06 of 28.0 works out pretty well with the spread sheet.

Yeah just clicked on it and says it is unavailable. I think filefactory only keeps stuff for 6 months.

Here's an iOS app for one, pretty accurate based on what I've done so far:
