How the numbers for Southampton v Swansea are calculated
Every figure on this page comes from the steps below – nothing is adjusted by hand.
Expected goals (λ)
Ratings fitted to league results (26 and 23 matches). 1.00 = average attack or defence.
| League avg goals | Attack | Opp. defence | λ (ratings) | |
|---|---|---|---|---|
| Southampton (home) | 1.64 | 1.23 | 0.91 | 1.84 |
| Swansea (away) | 1.30 | 1.02 | 0.72 | 0.96 |
λhome = μhome × Atthome × Defaway = 1.64 × 1.23 × 0.91 ≈ 1.84
| Total-goals source | Estimate | Weight |
|---|---|---|
| Team ratings | 2.80 | 45% |
| Statistical xG feed | 2.50 | 25% |
| Over/under 2.5 price | 2.80 | 30% |
| Blended total λ | 2.66 | 100% |
Split by team strength and the 1X2 balance → λhome = 1.89, λaway = 0.77
Poisson goal distributions
P(k goals) = e−λ · λk ÷ k!
