# Content FiveThirtyEight’s World Cup forecasting model used ESPN’s Soccer Power Index (SPI) — a system that combines game and player ratings to estimate a team’s overall skill level — to calculate odds of each country’s performance during the two stages of the World Cup. The probabilities, based on 10,000 simulations, were updated at the end of each match and aggregated into one file with the prediction date and time. # Acknowledgements The 2014 prediction data was featured in the FiveThirtyEight article [It's Brazil's World Cup to Lose][1] and the interactive infographic [2014 World Cup Predictions][2]. The World Cup match scores were scraped from the FIFA archive. [1]: https://fivethirtyeight.com/features/its-brazils-world-cup-to-lose/ [2]: https://fivethirtyeight.com/interactives/world-cup/
