I started off 2015 with an analysis of effective time in the J-League and which teams appeared to have a strong influence on it. To start off 2016 I do the same type of analysis but from a Bayesian perspective. My objective for 2016 is to take my analytics into more of a Bayesian direction — […]
Continuing from my previous post, I present the impact of Japan’s second-division clubs on the amount of effective playing time relative to the average in J-League Division Two (J2).Here’s some summary data on playing time in J2: The mean effective playing time in J2 during the 2014 season was 52 minutes 30 seconds. This average […]
Happy New Year to all of our readers! I hope all of you have a healthy and productive 2015.Let’s ease into the year with some analysis of effective match time in the 2014 J-League Division One competition. It’s similar to what I’ve done in previous analyses of the Premier League and J-League competitions, and you […]
Last year I wrote a series of posts on effective playing time in the top two J-League divisions at the mid-season and end-of-season marks. Further analysis of the numbers using an admittedly crude regression model indicated that some clubs have a significantly greater effect on the amount of playing time than others, for better or […]
In an earlier post I presented the estimated effective playing time in this summer’s World Cup matches over 90 minutes. (They are estimates because the raw data used to calculate effective time do not track the moments when the ball leaves the field of play.) Eight matches were decided in extra time, so for completeness […]
Since I started to apply mean time between fouls and mean time between stoppages to World Cup data, I was curious to find out if there was any correlation between these “mean-time-between” metrics and the effective match time. I’ll examine the correlation issues in this post.For reference, here is my post on MTBF for the […]
Continuing our application of “mean time between” metrics to the World Cup, I consider mean time between stoppages. (more…)
In my previous post I introduced the concept of mean time between fouls and mean time between stoppages. In this post I calculate mean time between fouls over all matches of the 2014 FIFA World Cup. (more…)
I was looking through this blog at the number of posts that I’ve written about referee performance, and it turns out that there are, as of this date, five posts under that category. Three of the articles are reviews of research publications, so I’ve actually written very little about the subject. That’s about to change […]
The entrails from the 2014 FIFA World Cup have cooled, and the thoughts of football fans have turned to domestic competitions and the Champions League, but I finally got myself out from maintaining and updating the Soccermetrics API to analyze data from the World Cup. I start with an assessment of effective playing time from […]
