Scientist from the Wissenschaftler of Münster have analysed the statistics of the German Bundesliga thoroughly and could characte🦂rise 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 ꦛthe Bundesliga a typical outcome of match is determined of coincidence by 86%. 14% are no coincidence and distinct💦 a top team from a potential relegation team.
Stunning: All teams🔴 in t♛he Bundesliga have about the same conversion of chances.
Home teams score more goals on average. Average 1,66 home and 1,20 away goals. There is an overall home advantag♕e but no evidence that in addition to that teams perform especially well at home. Thus, home strength is a myth.
Ty☂pically 3 goals are scored in a match. To be precise, the number of goals has decreased over time and now amounts to 2,8.
R✱ather not. 46 % of all wins are based upon a one-goal-margin.
No. Only about 25% of 🌃matches result ins draw. By implication 75% of matches have a w🐬inner!
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 awa♕y win, that figure already amounted to 33% in the season of 2010/2011.
🔯Extr🅠aordinary: On the last two match days about 20% more goals are scored than on average. So: Bet on higher results!
The goal differente of past matches is especially informative for the purpose of predictions. It is si🐼gnificantly more informative than the number of points. The expected amount of goals, on the other hand, is quite similar among all teams.
Goalscoring opportunities are a lot more informative for the sake of prognosis. Good teams show a slightly b꧟etter conversion.
The market value of a team as determined before the start of the season is extremely strongly correlated with their actual performance. Rule of thumb: Doubling of the market value = 10 additional poin🌺ts 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 performance🍬s of teams.
A football match is dominated by effects of coincidence. Additionally the performance level of offensꦓe and defense are correlated.
Without effects of coincidence, the difference of goalscoring opportunities 🐎would perfectly predict the performance level.
The goal difference is determined by effects of coincidence with 86% (match ᩚᩚᩚᩚᩚᩚᩚᩚᩚ𒀱ᩚᩚᩚday) or 29% (season) on average.
Fluctuaꩵtions of performance levels from match day to match day are, therefore, not statistically relevant. The changes of performances l✤evels take place during the summer break and only rare
There are no positive series. The concept of a “streak“ is, thus, void. Unfo🧔rtunately this does not apply for ne𝕴gative series - those do exist. As Andi Brehme famously put it: “When you got shit on your foot, you got shit on your foot!“
In the context of statistical preciseness, the conversion of effective ꦆgoalscoring opportunities is identical for all teams. For that reason the goalscoring opportunities are quite significanജt for the prediction of goals.
The performanceꦉ of promoted teams is astonishingly well predetermined. Significant deviations from the lower half of the tab⛦le (goal difference: -13 +/- 8) are, thus, extremely rare. For that reason a „march through“ is very special.
With the helꦍp of the market value and the effective differente of goalscoring opportunities you can come closer to the perfect prediction of the second half of the season..
No.💫 🐎In fact only in half of the cases the best 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 teꦰa🐎ms was negative. Looking at it statistically the effect is under 10%.
Of course we know! But it is enough for today, we 💃will let you know another rime.
