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 result🤡s 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 ar𓄧e influenced by the technical abilities of the players, the so called performance level, of both teams.
In the꧟ 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 th🀅e 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 advantage but no evidence that in addition to that teaꦡms 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 timꦚe and now amounts to 2,8.
Rather 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 mat🌟ches have 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 amounted to🐲 33% in the season of 2010/2011.
Extraordinary: On the last two m𒁏atch days about 20% more goals are scored than on average. So: Bet on higher res🌳ults!
The goalඣ differente of past matches is especially informative for the purpose of predictions. It is significantly more informative than the number of points. The expected amount of goals, on the other hand, is quite si𒐪milar among all teams.
Goalsc𒆙oring opportunities are a lot more informative for the sake of ✨prognosis. Good teams show a slightly better 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 mark💎et value = 10 additional points or a goal diffe🅺rence increased by 16 goals.
A season-specific avera෴ge Performance level of a team does exist. (Performance level = goal difference that a team scores aga🦄inst an average opponent)
The coincidence averages out during the course of the season. The longer 🥀the season has already prog𝐆ressed, the more reliable goals and opportunities display the performances of teams.
A football match is dominated by effects of coincidence. Additionally the performance level of offense and defe♌nse are correlated.
Without effects of co😼incidence, the difference of goalscoring opportunities would perfectly predict ෴the performance level.
The goal difference is determined by effects of coincidence with 86% (match day) or 29% (sea🃏son) on 𝓰average.
Fluctuations of performance levels from match day to match day are, therefore, not statistically relevant. The changes of performances levels take place during th💛e summer break and only rare
There are no posit🌊ive series. The concept of a “streak&ldq🐟uo; 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!“
In the context of statistical preciseness, the conversion of effective goalscoring opportunities is identical for all teams. For that reason the goalscoring opportunities are 🌟quite significant for the prediction of g𓆉oals.
The perfo🐼rmance of promoted teams is astonishingly well predetermined. Significant deviations from the lower half of the tabl💙e (goal difference: -13 +/- 8) are, thus, extremely rare. For that reason a „march through“ is very special.
With the help of the market va♒lue and the effective differente of goalscoring opportunities you can come closer to the perfect predic🍸tion of the second half of the season..
No. In fact only in half of the cases the best team wins and becomeꦰs German champion at the end of the season.
No. Statistically, there are no bogey te💎am. The scientist’s search for bogey teams was negative. Looking at it statistically the effect is under 10%.
Of course we know! But it is enough for today,🅷 we will let ꦐyou know another rime.
