I am reading through that book on database design, and it has helped me greatly in formulating an effective database for my research projects. The book has also shown me where I have made mistakes before in previous attempts at database development, and I hope to create something more useful this time around. Maybe I'll […]
Recently, I've spent a considerable amount of time discussing team and player metrics on this site, as well as some work on certain tournament formats, but it is clear that I need a better approach to collecting and storing match data. I've been able to demonstrate the efficacy of some of these metrics by collecting […]
Continuing with the discussion on adjusted plus/minus, below is a presentation that Wayne Winston made at the New England Symposium on Statistics in Sports last September on player and lineup analysis in the NBA. Wayne Winston is a professor at Indiana University's business school and the developer of the original adjusted plus/minus system (the Dallas […]
What I'm about to write about won't be news to those of you who attended the MIT conference, but I'll formally announce it on this site. I have started a sole proprietorship to conduct research and consulting related to soccer analytics. Its name is Soccermetrics Research and Consulting. The idea is to perform commissioned research […]
Apparently someone has written an article on the CONCACAF club/league coefficients on Wikipedia. It references both the current set of CONCACAF coefficients and my formulae for calculating them. There are some discrepancies that need to be addressed, however: The league coefficient is explained but the results of the league calculations are not presented. There are […]
I've already written a trio of review pieces on the Sloan Sports Analytics Conference earlier this month, but I have not written anything on my own impressions of the event and the areas in which the conference could improve. I just answered an evaluation form that the conference sent me a few days ago, and […]
The club and league coefficients for the CONCACAF region have been updated and are released below as a spreadsheet. I've discussed the coefficient format in previous posts like this one.Below are the domestic league ratings. All of the eleven nations listed below have been represented in the CONCACAF Champions League and have league coefficients greater […]
In the wake of recent conversations with people on and off this site, I realize that I really need to give a better explanation of the soccer Pythagorean formula than I have done previously. So in the following lines I hope to give a clear explanation that's understandable to everyone and 95% math free. (The […]
I noticed that I had been receiving a flurry of traffic from Québec all afternoon today. I found out that one of the reports at this French Canadian news site called Cyberpresse — the main football writer, actually — linked to one of my Soccer Pythagorean posts and tweeted this: According to the machine translator […]
I had some more time to think about the plus/minus scores published at the Climbing the Ladder blog, and I posted a comment to the post a few minutes ago. My critiques of the current version are that it uses solely 11v11 match situations, treats the periods of 11v11 play as one contiguous block, and […]
