# Wilkommen!

I've been getting a lot of hits from Germany in the past few days.  I don't know if they're all from the same person or not, but welcome and thanks for stopping by!  I took a couple of days off after writing about my extended Pythagorean over the past week, but there are some posts […]

# Pythagorean results: 2008-09 English Premier League

I've reached the final step in my effort to test my extended Pythagorean formula, using the 2008-09 English Premier League as a test case.  There was a last-minute snag in my plans, however.  I was looking over my equations one more time, and I decided to re-derive everything from the beginning, which is a good […]

# Pythagorean exponents in the 2008-09 English Premier League

A couple of nights ago I presented goal distributions for all twenty teams in the 2008-09 English Premier League season, in an attempt to calculate the exponent that would be used for my expansion of the Pythagorean.  I realized after my calculation that I needed to consider the sum of the squares of both the […]

# Goal distributions in the 2008-09 English Premier League

I'm using the 2008-09 English Premier League as a test case of the three-parameter Weibull distribution that is the basis of the Pythagorean formula.  Below I present the exponent values that I obtained from the least-squares estimation, as well as a few plots that show how the resulting Weibull distribution fit to the score data. […]

# My 15 seconds of fame

This isn't really soccermetrics-related, but it is about me in a technical field, so I'm posting it here.As a few people know, I work as an aerospace engineer in my day job.  I'm also an active member of the American Institute of Aeronautics and Astronautics (AIAA), which is the premier professional society in my field.  […]

# Test case for Soccer Pythagorean: English Premier League

As I said in my last post on my extended Pythagorean formula for soccer, I was in the process of compiling score data for the 2008-09 English Premier League season in order to test this formulation.  The first step was to fit the data to a Weibull probability distribution in order to estimate the alpha […]

# Updated CONCACAF club coefficients, 2009-10-24 version

I've updated my CONCACAF club/league coefficients with data from the now-completed group stage of the 2009-2010 CONCACAF Champions League.  My latest spreadsheet can be found below, in OpenOffice and Excel formats.CCL_NatlCoefficients0910_20091024.odsCCL_NatlCoefficients0910_20091024.xls

# The Soccer Pythagorean document

I completed my Soccer Pythagorean document a couple of days ago, but for some reason I had the hardest time developing a PDF file (I used LyX).  I figured it out tonight and I'm linking it to the site now.  I greatly appreciate your comments.Download PythagDerivationMORE (23 October, 10:50pm): I'm compiling some score data from […]

# Update on the Soccer Pythagorean derivation

** BUMPED to the top with updates added **I want to give an update on my efforts to derive a Pythagorean (or Pythagorean-like) formula for use in soccer.  As I said in other posts, the most challenging part is coming up with the term that captures the probability of a drawn result.  This is rather […]

# MIT’s Sports Analytics Conference

I was trawling for conferences for statistical analysis in sport, and I came across this conference at MIT's Sloan School of Business in March.  From the looks of it, they don't have any presentations on sport analytics from anyone in the soccer world.  They should. UPDATE: This call for papers at the Conference might be […]
