It is the next version of a rank of ranks. Kenneth Massey has made a remarkable thing - has collected about hundred ranking systems of College Football teams. And having assumed, that as behind everyone ranking authors stand and all of them are equal and are the experts as though armed with mathematics. And time so that is naturally simple to calculate certain average ranking, for example, by summing ranks of teams. As has truly noticed by Kenneth Massey models of an estimation of validity of ranks much. Probably as much how many models of ranks. More or less the general structure probably is fair ESTIMATION of the MISTAKE = IMPORTANCE of MISTAKE * SIZE of MISTAKE Here: IMPORTANCE of MISTAKE = SIZE of MISTAKE = ESTIMATION of DEFEATED RANK - ESTIMATION of WINNER'S RANK It results in beautiful expression: ESTIMATION of MISTAKE = In the previous version the elementary estimation of the RANK of participants was used 1. RANK ESTIMATION = N - RANK However it is only one of possible elementary arithmetic expressions. To look as influence various estimation models of the RANK, I used one another expressions 2. RANK ESTIMATION = N / RANK - gives more "attention" to the top rank The size of a mistake is submitted by a difference of estimations of ranks. If we as an estimation of a rank take the number of teams of below given rank (N - R) that will turn out, that the SIZE of a mistake is identical to a case the 10 th team wins 1-st and when the 110-th team) wins at 101. Something prompts me that it is incorrectly. If as an estimation of a rank to take N/R that the Size of a mistake will be N / RL - N / RW = N * (RW - RL) / RW*RL For pair RW = 1 and RL = 10 VM = N * (1-10) / 10 = 0,9 * N For pair RW = 101 and RL = 110 VM = N * (101 - 110) / (101 * 110) = 0,0009 N It is more similar to the truth The importance of a mistake it is submitted by the sum of estimations of ranks If as an estimation of a rank âîçìåì the number of commands (teams) of below given rank (N - R) it will turn out is simple that the IMPORTANCE of a mistake is identical to a case when 51-I a command (team) win against 50-th and when 101-I lose 1-st. Something and in this case prompts me that it incorrectly. Let's look, that turns out if as an estimation of a rank to take N/R. For pair RW = 51 and RL = 50 IM = N * (51 + 50) / (50 * 51) = N / 50 For pair RW = 100 and RL = 1 IM = N * (100 + 1) / (100 * 1) = 1 * N And it is more similar to the truth too :) And so the estimation of a rank as N/R has advantage before N - R. And how do you think? 22 November 2003 I'll Update this table as soon as Kenneth Massey update his COMPILATION/ Wait a moment :)) You can see that MASSEY'S CONSENSUS RANKING is not the first. But let's wait for complete data So, we have three rank - lists. I do not know that with them to do. Therefore has gone on the worn way simply summed ranks. Also that has turned out.
