Re: Offensive Power Rankings for 2008
Can we get an OPR for divisions based on overall performance instead of individual regionals?

 . That is all it means. OPR correlates strongly with scoring ability, but it also correlates with other things such as teamwork (teams that get in the way of their alliance partners would have lower OPRs) and rule-abiding (see those negative numbers? those teams tended to take penalties). Someone who has scouting data on every single team in FIRST might be able to tell you if you're literally the 14th-highest scoring robot in Galileo. However, since I don't think anyone actually has that much data, this is a nice stand-in. It is certainly something to be proud of.Quote:

Re: Offensive Power Rankings for 2008
How about some statistics on the individual divisions like mean, median, standard deviation, and whatever else might be interesting. I'd like to throw some fuel on the best division debate by seeing how they stack up against each other in OPR.

Re: Offensive Power Rankings for 2008
I noticed some people were requesting DPR scores. While the meaning of a DPR number isn't as straightforward as OPR, I think we may be able to improve the OPR calculation by taking it into account. If a team tends to play heavy defense, the teams they play against shouldn't have their OPR reduced when they play below average. Plus I love linear algebra so this gave me an excuse to use it.
<complex math warning> So here's the equation: Code:
( M -N ) ( p ) = ( s_t ) ( N -M ) ( d ) = ( s_o ) M = n x n matrix with M(ij) = # of times i played with j. M(ii) = # of times i played. (same as M from before) N = n x n matrix with N(ij) = # of times i played against j. N(ii) = 0. p = n x 1 column vector of OPRs. p(i) = OPR for team i. (same as p from before) d = n x 1 column vector of DPRs. d(i) = DPR for team i. s_t = n x 1 column vector of total scores. s_t(i) = Sum of all of team i's match scores. (same as s from before) s_o = n x 1 column vector of total opponent scores. s_o(i) = Sum of all of team i's opponents' match scores. In other words, the first n equations add all the offense played by team i's allies, subtracts all the defense played by team i's opponents, and equates that with team i's total score. The second n equations sums all the offense played by team i's opponents, subtracts all the defense played by team i's allies, and equates it with team i's opponents' total score. We can rewrite the equation as Ax = y where A = (M -N; N -M), x = (p; d), and y = (s_t; s_o). In the data set I used, there are 2 isolated sets of teams that played no matches with teams outside their set: the Israeli and non-Israeli teams. We can separate these sets and write an equation for each one, and I think it's easier if we do: Code:
A_1 * x_1 = y_1 A_2 * x_2 = y_2 Code:
M(11)*p(1) + M(22)*p(2) + ... + M(nn)*p(n) = 1.25 * (sum(s_t) / 3) Code:
( E 0 ) ( p ) = 1.25 * (sum(s_t) / 3)
( d )
E = ( M(11) M(22) ... M(nn) )
Code:
A = ( M -N )
( N -M )
( E 0 )
</complex math warning> I ran this against the first csv Greg posted and here are the results (top 50, ordered by OPR): Code:

The two OPRs tell you slightly different things about a team. The old OPR tries to tell you how much a team actually scored each match. The new OPR tries to tell you how much a team could have scored each match if there was no defense. They are both potentially useful numbers. Finally, knowing both OPR and DPR does allow you to better predict the score of a match. If you define error as: Code:
error = actual_red_score - ( p(red1) + p(red2) + p(red3) - d(blue1) - d(blue2) - d(blue3) ) Method #1 MSE = 245.0446, ME = 12.306 Method #2 MSE = 180.8867, ME = 10.514 So it's better at predicting past scores. Is it better at predicting future scores? I guess we'll see.

Re: Offensive Power Rankings for 2008
Jay, this is some very inpressive Linear Algebra. This is pretty awesome!
Two thoughts: Would it be possible for you, at some point, to post all DPR rankings from the overall data set? Also, maybe something more interesting for the results, could you try and solve for which correction factor (in the arbitrarily chosen equation) makes for the lowest ME? Maybe that can make it even more vaulble of a tool. I'll also shoot you a PM with another idea I have to make OPR (and probably DPR) even more meaningful.

Re: Offensive Power Rankings for 2008
Now that its all over, would anyone like to post OPR based on just matches at nationals (separately for each division). I am interested in observing how teams did at an individual regional compared to nationals.

Re: Offensive Power Rankings for 2008
I would like to say -- I love numbers and data. I predicted the scores of all our qualification matches and ( other than the first match that had two of our robots quit ) the scores were within 10% most of the time -- very close !!! We also had the 15th highest OPR in Archimedes -- we ended up the 17th seed -- again very close. Based on the numbers, I said we would go 6-1 -- we were 5-2.

We were 15th in Galileo in OPR, however, we dont have a hurdler. All of our points are in auto/laps/assists. We thought we would go 5-2, but our matches didnt go as planned so we went 3-4. I like the details of this and i really appreciate it, i have been looking for something this detailed.
