Understanding the Poisson Model
The Poisson Distribution is a powerful statistical tool that helps predict the probability of a given number of events occurring in a fixed interval of time or space. In football, this "interval" is the 90-minute match, and the "event" is a goal. By analysing historical data, we can establish average goal rates for teams and leagues, which become the inputs for our model.
Attack & Defence Strength
The model's core lies in calculating each team's relative strength. We determine a team's 'Attack Strength' by comparing its average goals scored to the league average. Similarly, 'Defence Strength' is found by comparing its goals conceded to the league average. These metrics tell us, statistically, how much better or worse a team is than the average league participant, both offensively and defensively.
Calculating Expected Goals
The calculator doesn't just use a team's scoring record in isolation. It projects performance for a specific match by multiplying the home team's attack strength by the away team's defence strength, and vice-versa. This cross-referencing provides a more nuanced 'Expected Goals' figure for each team in the upcoming fixture. This is the crucial 'lambda' (λ) value in the Poisson formula.
Once we have the expected goals, the calculator can compute the probability for each team to score 0, 1, 2, 3, or more goals. From there, it can determine the probability of specific scorelines (like 1-0 or 2-2), the chances of the total goals being over or under a certain number, and the likelihood of both teams scoring. These probabilities can be a great starting point for identifying value in betting markets. For more complex bets, you might want to use a parlay calculator to combine odds, or an odds converter to see probabilities in different formats.
