# Soccer betting mathematical model

processes of betting companies, based on a case study of Metric Gaming. Being great football fans ourselves, as well as students of mathematics. About my own "journey": I have a PhD in applied mathematics and was interested in gambling and economics. So I started with the data from Joseph Buchdahl (here). Mathematical modelling of football If they could equalise (and I'm not betting against them) I Fivethirtyeight Global Club Soccer Rankings. WAS NEO BEFORE ETHEREUM

It was originally invented for and used in chess, but throughout the time it has been successfully applied to a variety of other sports including soccer see [ 13 , 3 ] , tennis [ 14 ] or Australian rules football [ 15 ]. It was shown that this ELO approach was superior to models based on an ordered probit regression approach introduced by Goddard [ 17 ] but inferior to betting odds.

Betting odds Betting odds can be seen as an aggregated expert opinion reflecting both the judgement of bookmakers and the betting behavior of bettors. However, it is a completely different form of expert opinion compared to studies where experts are asked to perform forecasting tasks in an experimental environment.

Whereas those experts usually do not have to fear negative consequences from inaccurate forecasts, offering inaccurate odds will have serious financial consequences for bookmakers. This could be a reason why betting odds were shown to be clearly outperforming soccer tipsters publishing their forecasts in sports journals [ 8 ]. Hvattum and Arntzen [ 16 ] show that in general betting odds possess an excellent predictive quality and perform better in forecasting soccer results than various quantitative models.

A consensus model based on betting odds of various bookmakers was shown to provide more accurate forecasts on the European championship in soccer than methods using the ELO rating and the FIFA World Ranking [ 11 ]. Kovalchik [ 14 ] even investigates eleven forecasting models in tennis and finds that none of it is able to outperform betting odds in forecasting singles matches.

Without denying the general predictive power of betting odds, it is worth noting that there are empirical indications on the imperfectness of betting odds as shown in [ 18 ] or in the extensively documented favorite-longshot bias see [ 19 ] for an overview. Moreover, it is worth noting that various model based approaches were yielding positive betting returns when deducing betting strategies from the forecasts [ 20 — 22 ] among others. A major part of the aforementioned studies focuses on comparing the four different sources of forecasts or different approaches for the same source of forecast.

As a wide consensus exists that betting odds have proven to be a powerful instrument in forecasting [ 23 ], betting odds are routinely used as a quality benchmark for testing the predictive quality of mathematical approaches [ 14 ]. By doing this, betting odds and mathematical models are outlined as contrary approaches for the same forecasting task, instead of mixing the power of both approaches to create new forecasting possibilities.

So far, hardly any study has tried to revert the forecasting process using existing forecasts from betting odds to draw conclusions about the qualities of the teams, obtain team ratings and thus contribute to the performance analysis of teams. Leitner et al. However, no betting odds from single matches are considered for establishing team ratings. Although the predictive quality of betting odds is frequently stated and the extensive information reflected in the odds can undisputedly be seen as an important advantage of betting odds, the question of how valuable betting odds of prior matches are for forecasting future matches has not been tackled so far.

This study extends prior research in various aspects. We present a novel model that is able to combine the advantages of mathematical approaches with the information advantage of betting odds. By design, the model is not expected to improve forecasts from betting odds, but it aims at developing a framework that enables us to investigate the transferability of prior forecasts to future forecasts, construct a rating that improves classical rating methods and thus use forecasting methods to gain improved practical insights into performance analysis.

In detail, we examine the question whether betting odds known prior to a match are of higher value for forecasting purposes than the result known after the match. The rating used as an intermediate step of the forecasting model can be interpreted as a reversal of the forecasting process as the quality of a soccer team is deduced from prior forecasts.

We use this rating to demonstrate improvements to traditional rating methods and how the information included in betting odds can effectively be extracted to be used in practical analysis, e. Moreover, we demonstrate how the ELO-Odds model can be used for analyzing the quality development of individual teams over time or the explanatory power of league tables.

Finally, we demonstrate a lack of theoretical foundations concerning rating models that take advantage from the network structure of matches by applying match results to the ratings of uninvolved teams. Overall, more than international matches were considered adding up in a total database of nearly 15, matches. The models examined throughout this paper are based on the following data for each match: match date, home team, away team, home goals full time , away goals full time as well as betting odds for home win, draw and away win.

To avoid bookmaker-specificity and obtain a best possible reflection of the betting market, all betting odds used in the analysis are averaged based on available betting odds of various different bookmakers. Except for isolated cases, the average betting odds are based on five or more bookmakers in international matches and 20 or more bookmakers in domestic matches.

The difference between international and domestic matches is due to the extent of information and level of detail available at the respective data source. The matches Cagliari vs. Roma Pescara The final matches from Champions League and Europe League were completely excluded from the data set as these are played at a neutral location. When performed correctly, return based betting strategies can further increase your chances of protecting your bankroll and give rise to more consistent returns.

This is not as complicated as it sounds; if you check out the odds pay out table , you can see the different returns that you would receive for the different odds. The hard part if finding selections that are more likely to win, that is where the trouble sometimes starts for many bettors. Arbitrage betting Is a technique that can be easily confused with matched betting, but if you can tell the difference between arbitrage betting and matched betting , you have the possibility to secure a better long-term understanding of football and sports betting.

Arbitrage betting is a combination of understanding the betting odds and the different selections to ensure that you have the best opportunity to secure the best monetary outcome for your selections. There are a couple of posts on this website, which go into more detail about arbitrage betting systems and its close cousin; matched betting , so read through when you get a chance, as this could help you to find more favourable selections over the long term.

Pure mathematical betting strategies A couple of mathematical betting systems and strategies are highlighted within this section, so you can view the best options for your selections. This is where some punters and less experienced bettors can lose their heads and start betting with their heart.

This is always a mistake, so before you keep reading; I recommend that you check out the how to improve your betting mindset blog post, where I go into slightly more detail about the different betting areas and how you need to focus on what can help you become more successful. Martingale betting system This approach is based on starting with a small stake and doubling your stake after each loss and then starting again when you win.

In theory, if you have infinite wealth and you manage to wager your infinite stake with a bookmaker or collection of bookmakers , then this strategy could work over the long term. There are obviously, two main issues with this one; no-one has infinite wealth and most bookmakers have maximum bets.

So, in an expected long losing sequence , this could really damage your chances of regaining profits. Review this betting system and other online sources with extreme caution Labouchere betting system The Labouchere betting strategy is sometimes compared to the Martingale betting system, which is a way to reduce the large risks associated with the martingale strategy.

#### Author s : Wunderlich, Fabian; Memmert, Daniel Abstract: Betting odds are frequently found to outperform mathematical models in sports related forecasting tasks, however the factors contributing to betting odds are not fully traceable and in contrast to rating-based forecasts no straightforward measure of team-specific quality is deducible from the betting odds.

Rankings The predictive character of rankings is questionable for several reasons. Brighton] Between them the attack parameters, defence parameters and home advantage parameter give 41 quantities to be evaluated. A more thorough test of the accuracy of the model involved comparing both the outcomes home win, away win or draw and scores on a game-by-game basis.
