This is V1 of X-Goals which is an alternative method to score a match.

XGoals uses the weighting approach of 0.15 (corners), 0.2 (shots on) and -0.1 (cards).

Cards increases by 1 for a player’s first yellow card, and by 2.5 for a second yellow or a red (motivated by sportingindex.com weightings). Currently corners and shots on are modelled using the normal distribution, with 95% of values lying in the range [0, 2 times the expected value]; this means the spread is set to be half the expected value (this is motivated by historical behaviour for teams over a whole season, and clearly that’s not going to be ideal as it doesn’t account for the strength of the opposition properly. Don’t judge too harshly as this is just Version 1!). The distribution for the cards follows a Poisson distribution.
