In a previous post, I wrote about match management by referees at the 2018 FIFA World Cup. Effective match time is part of that analysis, and it is possible to infer the average amount of effective time during the tournament. This post will break down effective match time over all 64 matches played.As is the […]
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 […]
Last night, I tweeted a teaser for this post that said that the median effective playing time in Argentina’s Primera División matches is in the vicinity of 48 minutes, which is very low for a domestic football competition: Por mis cálculos, la mediana del tiempo efectivo de juego en 1ra División Argentina 16/17 se queda […]
The new season of the J-League kicked off tonight, so for completeness’ sake I’m extending my analysis of club impacts on effective time in the J-League to its lower divisions. The analysis is similar to previous work with a slightly different way of presenting the results.The effective match data was collected by DataStadium as part of an […]
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 […]
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 […]
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 […]
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 […]
In my previous post on the subject I applied the mean centering technique to the regression that I ran on effective time data in the 2010-11 English Premier League. I’ve been working with J-League data from this recently concluded season, so let’s refine that analysis for completeness sake.If you’re just joining us, the regression analysis […]
First of all, Happy New Year to all our readers! I wish you all a productive, healthy, and happy 2014.I want to continue some work that I was working on last year — 24 hours ago, in fact. In my previous post I conducted a regression analysis of team effects on the amount of time […]
