Stavo cercando qualche fonte Open Data sui Mondiali di calcio 2014 ed ho trovato questo interessante studio
"Among the variables analysed, those that had an effect on the probability of England winning a match were found to be the stadium
temperature, the stadium altitude, distance from London, the nationality of the referee and opposing nation, the colour of shirt worn and team formation. The variables in our study that were found to affect the probability of a player scoring a penalty during a shootout were the player’s position, the length of run-up, where on the boot the ball was kicked from, the player’s hair type and where the ball was aimed. In terms of saving penalties it was found that how the goalkeeper moved when the ball was kicked impacted the probability of saving the penalty."
