Four years ago I used the occasion of the 2014 FIFA World Cup to write my first articles on referee performance analytics. In the absence of tracking data these analytics have focused more on the management of matches by the 25 center officials than the veracity of in-match decisions or proximity to major events. I’ve […]
Last season I wrote a few articles on referee performance metrics in Argentina’s Primera División. This season I present the same thing for the first half of the re-branded Superliga.The referee-associated metrics that I have collected for each match include yellow/red cards, penalties given, time added on at end of first and second halves, mean […]
At the midpoint of the 2016-17 Argentine Primera División season, I conducted an analysis of the refereeing performance in the competition that focused more on match management — time added on, time between stoppages, and effective time. At the conclusion of the season, I return to this analysis and include a few metrics that the […]
The following chart presents metrics that in their totality provide a picture of the referee’s management of matches worked in the 2016-17 Primera División Argentina.Data supplied by DataFactory.Here’s the key for the table columns, aside from the obvious. P1 and P2 refer to first and second periods, respectively. All time is in seconds.Added: Stoppage time added […]
En el fútbol, el análisis de los árbitros es un tema muy delicado. La mayoría del análisis se hace en una manera muy simplista y lleva poco valor. Suele tratar de las cantidades de faltas, tarjetas, y penales marcados por el árbitro, y a veces el análisis está organizado por los cuadros en los partidos […]
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 […]
I’ve been banging on the “Hey, let’s model effective match time!” drum for a few posts now, and I’m ready to move on to something else, but I want to present one more extension. You can read some of my previous work in the Match Quality Metrics category of the blog.I want to answer this […]
