GOTW Whackometer - Week 3

Here are the results for the Week 3, Game-of-the-Week Whackometer, which attempts to see whether one (or more) of the GOTW judges are "whacko".

Name Week-1 Week-2 Week-3 Average
Jeff  0.792  0.319 -0.149  0.321 
Greg  0.471  0.307  0.522  0.433 
Arun  0.493  0.563  0.164  0.407 
JimD  0.493  0.505  0.329  0.442 
Mike  0.661 -0.058  0.009  0.204 

Remember that a number closer to 1.000 means that the judge agreed with the collective wisdom of the other judges, a number closer to -1.000 means that the judge disagreed with the collective wisdom of the other judges, and a number close to 0.000 means that the judge neither agreed nor disagreed with the collective wisdom of the other judges.

This past week, the results were pretty varied. Greg agreed most with the other judges, while Jeff somewhat disagreed with them. Michael, once again, was independent of them.

For all three weeks, however, each judge still has a positive number, indicating that (overall) each judge agrees with the other judges to some degree.

Thus, so far, no whacko.

USCL Ratings and Power Rankings: Week 3 (2009)

UPDATE. I forgot to increase the current week counter on the spreadsheet, and thus what I posted was wrong. Mea culpa. Thank you for HA81 for the constructive criticism which made me go back to look at this.

Here is the correct list.

USCL 2009 Week 3 Power Rankings (CORRECTED)

1 -	San Francisco	1.000
2 -	Seattle	0.931
3 -	New Jersey	0.922
4 -	Miami	0.883
5 -	New York	0.843
6 -	Dallas	0.813
7 -	Arizona	0.801
8 -	Tennessee	0.737
9 -	Philadelphia	0.718
10 -	Chicago	0.699
11 -	Boston	0.691
12 -	Queens	0.562
13 -	Carolina	0.543
14 -	Baltimore	0.527

I had been asked by United States Chess League Commissioner, Greg Shahade, to also publish power rankings for the 14 USCL teams. Note that these Power Rankings are entirely based on mathematical formulas; there is no subjectivity at all. They are calculated using the same formula that used previously on this website. Top team always get a 1.000, the remainder of the teams get numbers less than that.

GOTW Whackometer, Part 2

Well, I woke up yesterday morning, with a sick feeling that the co-linearity problem was actually a real problem, given the population size. So, I redid the correlations, but this time correlated a judges score with the sum of the points of the other judges. In this way, a judge's own points are not considered in the correlation.

The results are rather interesting.

Name Week-1 Week-2 Average
Jeff  0.792  0.319  0.556 
Greg  0.471  0.307  0.389
Arun  0.493  0.563  0.528  
JimD  0.493  0.505  0.499
Mike  0.661 -0.058  0.302

Mike's correlation in week 2 is pretty close to 0, which suggests that he had almost no correlation with the other judges. However, in both weeks, all the judges are reasonably similar in their correlations. Two weeks is not a very good sample.

HOWEVER, note that this is for the games that were selected. Remember that there are about 20 other games, that ALL judges marked as 0. Including these games would lead to a much higher correlation for everyone.

2009 USCL Ratings Week 2

2009 USCL Inaugural Raring List

Welcome to the (unofficial) USCL Ratings List of 2009! I am pleased to provide this service again to all the USCL fans out there.

The details of the calculations of this rating system have been described elsewhere, but to summarize... (a) it uses a modified Glicko system; (b) there are different scores for a draw if your team won or lost; (c) it accounts for color in your score expectancy; (d) uncertainty scores are automatically raised at the beginning of a season; (e) initial rating assignment depends on the board that you played; (f) all games are given equal weight (regular season, playoffs, tiebreakers).

That being said, the same conditions apply to each published list. First, the player must have played at least three lifetime games in the USCL, and second, the player must be active in the year the list is published.

Here is the initial list for 2009 - there are so few names on the list, because there are fewer players active in 2009 (so far).
