“…In this article we follow the retrospective approach and we present a nested generalized Poisson regression model with zero-inflation for the prediction of the scores of single matches, where the model is solely based on the Elo ranking and matches of the participating teams since 2016, where we additionally take the location of matches into account Since the FIFA World Cup 2022 is a complex tournament, involving important effects such as, e.g., group draws (e.g., see Deutsch (2011)) and dependences of the different matches, Monte-Carlo simulations are used to forecast the whole course of the tournament. For a more detailed summary on statistical modeling of major international football events, see, e.g., Groll et al (2015) and references therein.…”
