A Gecko Edge analysis is a sequence of modelling steps, each feeding the next, built for football rather than borrowed from a general tool. The model first estimates how many goals each team is likely to score, converts those estimates into the probability of every plausible scoreline, corrects those probabilities for the ways real football deviates from pure chance, and then translates them into market prices and an edge against the bookmaker.
In named steps: the model builds full-time scoring rates for each side, then derives first-half rates from them. It turns those rates into a Poisson grid of possible scorelines, applies a Dixon-Coles correction for the way real results cluster (low-scoring games and certain scorelines behave differently from a naive model), and renormalises so the probabilities add up correctly. From that corrected grid it reads off the probability of each market: Over and Under lines, Both Teams To Score, Match Result, and the rest. A Bayesian blend then weighs those probabilities against empirical league rates, so the output reflects both the specific fixture and what happens in that league over time. Finally the model compares its view against the live market, flags where the two diverge, and expresses the result as expected value and edge.
The point of the structure is consistency. The same fixture in the same state runs through the same steps, so you get a repeatable calculation rather than a different opinion each time you ask. The Sanity Score on the output reflects how strongly that chain of steps agrees on the result, and the +EV figure is the gap between the model’s fair price and the bookmaker’s price at the moment you run it.
The exact weights, correction values, and internal field names inside these steps are product detail held with the technical team, so this overview stays at the level of what each stage does.
