Quintessa mathematicians and scientists enjoy analysing numbers. Over the last few months, Simon Rookyard and Jodie Stone have further enhanced Quintessa’s algorithm for sports team rating and result prediction that was used to predict results for the UEFA Euro 2020 competition. It will be put through its paces during the upcoming FIFA World Cup - Qatar 2022.
It's crunch time! Having already used our "N-Estimates" algorithm to predict both the group and Last-16 stages of the FIFA World Cup - Qatar 2022, N-Estimates is now being put to the test for the final stages of the competition! The team’s ratings have been updated and our final predictions can commence - the plots can be found below. (These will be updated as the final stages of the World Cup progress.)
The prediction plots indicate the likelihood levels of various possible results. The x- and y- axes represent potential numbers of goals scored by each team. The team on the x-axis wins if the predicted scoreline is below the blue dashed line and the y-axis team wins when above. (A predicted scoreline on the blue dashed line is hence a draw.)
The colour of the plotted points denotes the probability of each given scoreline. This is scaled with a high probability plotted in orange and a low probability in blue. The plotted scoreline embellished with a cross denotes the most likely result. The solid orange line represents the most likely difference in performance between the teams during the match, expressed as a goal difference. (As this is based on non-integer mean ratings for the two teams, it is not necessarily an integer value.) The 1σ uncertainty range for this predicted goal difference is given by the two dashed orange lines.
FIFA World Cup Quarter-Finals
Will Portugal do as well as expected? Will the other teams be fighting it out in penalties!?
FIFA World Cup Semi-Finals
FIFA World Cup Final (and 3rd Place Play Off)
The margins are very tight, but the algorithm is predicting a tournament win for Argentina!
After its initial publication, this article has been updated to add extra predictions as follows:
- 12 Dec, 2022: Argentina vs Croatia, France vs Morocco.
- 16 Dec 2022: Croatia vs Morocco, Argentina vs France. Corrected shortly after initial publication to state that the tournament is predicted to be won, marginally, by Argentina, not France.
Quintessa is not affiliated in any way with FIFA. Its application of the N-estimates algorithm to the FIFA World Cup 2022 competition is an independent and non-commercial endeavour.
