Scientist from the Wissenschaftler of Münster have analysed the statistics of the German Bundesliga thoroughly and could characterise a football match as a Poisson-Process and like that made football results calculable. The crucial finding of the scientists is that goals in football are a product of coincidence. Goals, however, aren’t a sole game of dice but are influenced by the technical abilities ♍of the players, the so called performance level, of both teams.
In the Bundesliga a typica𝔍l outcome of match is determined of coincidence by 86%. 14% are no coincidence and distinct a top team from a potentia🧔l relegation team.
Stunning: All teams in the Bundesliga have about the s♓ame conversion of chances.
Home teams score more goals on average. Average 1,66 home and 1,20 a🅺way goals. There is an overall home advantage b𒉰ut no evidence that in addition to that teams perform especially well at home. Thus, home strength is a myth.
Typically 3 goals are scored in a match. To be precise, the number of goals has decreased over time and now amounts🅘 to 2,8.
Rather not. 46 % of all wins are based up𒅌on a one-goal-margin.
No. Only about 25% of matches result ins draw. B🌸y implication 75% of matches haꦬve a winner!
Yes, but since the middle of the 80s, the number of away wins is constantly getting bigger. While during the 70s distinctively more than 20% of matches resulted ins away win, that figure already amou🤪nted to 33% in the season of 2010/2011.
Extraordinary: On the last two match days ab𝐆out 20% more goals are scored than on average. So: Bet on higher results!
The goal differente of pas💞t matches is especially informative for t𝄹he purpose of predictions. It is significantly more informative than the number of points. The expected amount of goals, on the other hand, is quite similar among all teams.
Goalsco💫ring opportunities are a lot more informative for the sake of pr🅺ognosis. Good teams show a slightly better conversion.
The market value of a team as determined before the start of the season is eꦍxtremely strongly correlated with their actual performance. Rule of thumb: Doubling of the market value = 10 additional points or a goal difference increased by 16 goals.
A season-specific average Performance♏ level of a team does exist. (Performance level = goal difference that a team scores against an average opponent)
The coincidence averages out during the course of the season. The longer the season has already progressed, the more reliable goals and opportunities display the perf🃏ormances of teams.
A football๊ match is dominated by effects of coincidencꦕe. Additionally the performance level of offense and defense are correlated.
Without effects of coincidence, the difference of goalscoring opportunities would perfectly predic🐓t the performance level.
The goal difference is determined by effects of coincidence with 86% (match day) 🐼or 29% (season) oღn average.
Fluctuatio𝓰ns of performance levels from match day to match day are, therefore, not statistically relevant. The changes of performances levels take place during the summer break and only rare
There are no positive series. The concept of a “streak“ is, thus, void. Unfortunately this does not apply for negative series - those do exist. As Andi Brehme famously put it: “When you got shit on your foot, you got shit on your foot!&ld🧜quo;
In the context of statistical preciseness, the conversion of effective goalscoring 🎶opportunities is identical for ಞall teams. For that reason the goalscoring opportunities are quite significant for the prediction of goals.
⛦The performance of promoted teams is astonishingly well predetermined. Significant deviations from the lower half of the table (goal difference: -13 +/- 8) are, thus, extremely rare. For that reason a „march through“ is very special.
With the help of the market value and the effective differente of goalscoring opportunities you can come closer to the perfect prediction of the seco🦹nd half of the season..
No. In fact only in half of the cases the bꦬest team wins and becomes German champion at the end of the season.
No. Statistically, there are no bogey team. The scientist’s search for bogey teams was💝 negative. Looking at it statistically the effect is under 10%.
Of cou🐼rse we know!ꦯ But it is enough for today, we will let you know another rime.
