Here are the #WorldCup2022 #draw #probabilities for #Serbia (+/- 0.3%) based on 100K simulations of the official procedure, assuming Mexico & USA qualify directly. Two pot scenarios are considered depending on whether Canada will be in Pot 3 or 4 #Qatar2022 #WorldCupDraw

UPDATE with 1 million simulations: Here are the #draw #probabilities for the playoff of the #EuropaLeague (+/- 0.1%, based on 1M simulations). Runners-up of Europa League group stage play 3rd-place teams from #ChampionsLeague group stage #UEL #UELdraw

It is fun to note how the #draw #probabilities of the round of 16 of the #ChampionsLeague would have changed if UEFA drew group winners first (right) instead of group runners-up (left). The draw procedure matters! #UCL #UCLdraw #Probability #mathematics

Here are the correct #draw #probabilities for the round of 16 of the #ChampionsLeague , based on 400,000 simulations of the OFFICIAL PROCEDURE (which is quite complicated). Error +-0.1%. Watch how likely @FCBarcelona - @ChelseaFC is! 41%! Then PSG-CHE, BES-CHE at 29%

Here the #draw #probabilities of the #EuropaLeague Ro32 now based on 200K simulations of the OFFICIAL PROCEDURE (up to small sampling error). Prob is quite uniform. Sporting vs Espanyol, ManU, Sevilla, Celtic most likely (~8.7%). Salzburg vs Lev, Shak, Olimp least likely (~5.5%)

I was interviewed by @RiskDotNet about volatility modeling and football in the latest episode of their podcast @Quantcast . We talked option pricing, path-dependent volatility, SPX-VIX, and World Cup draws and formats. Enjoy!

#FIFA finally announced #WorldCupDraw procedure. Here are the draw #probabilities for #Brazil , based on 100,000 simulations using the official rules. Small fluctuations due to finite nb of simulations. Watch the impact of geographic constraints #Russia2018

What a fairer 24 team UEFA Euro could look like. My new article was just published in Journal of Sports Analytics (open access to all). UEFA has adopted my "Suggestion 6" (see Table 5) for the new bracket of the #Euro2020 !

Note that the probabilities would have been completely different if Chelsea had not conceded a goal in St Petersburg in injury time!
