Betfair’s internal team of Data Scientists have created an AFL Prediction Model. Largely influenced by ELO ratings, the model creates probabilities for every game. Including finals. You’ll often notice discrepancies between the AFL odds on the Betfair Exchange and the probabilities.
Some clients scrape this AFL predictor every week and feed it into their own models. Factors such as injuries and weather aren’t considered in the assessments but can be manually considered to give you an added edge.
If you’re interested in creating a similar resource, we strongly recommend checking out Betfair’s Github. You can find resources there that will help you create your own AFL Prediction Model.
