The organizing committee of the 2015 International Conference on Mathematics in Sport (MathSport International) has announced its call for papers. Next year’s conference is hosted by Loughborough University in the UK from 29 June – 1 July 2015. (more…)
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 […]
Knowing when the ball is out of play (“ball-out” events) in football is important in order to calculate effective playing time and the possession metrics of the two teams. But what do you do when you don’t have ball-out data? In this post I present a calibration tool to estimate match time lost due to […]
The summer transfer window is now closed, so it’s a good time to update the projections for this season’s Eredivisie. (more…)
