Premier League Preview

I have a mathematical ranking system devised for the English Premier League. The system is based solely on results so far in the English Premier League and it can both rank the teams and give predictions for future games. The system takes into account home and away advantages and gives each team an offensive and defensive rating that is used to determine the expected number of goals scored for both teams in the match. Soon I will probably give a more in depth look into how both the rankings are created and I will give a numerical value for all the rankings and offensive and defensive ratings. Those of you more interested in the statistical side of things may be interested to note that the scores follow a Poisson Distribution with mean based on the factors listed above.
For now, the ratings can be used for the most interesting thing, predicting match results! I will give the five most likely match outcomes along with the probability of win, draw, or loss for each team. As always, home team listed first! For a more comprehensive preview of this weekend’s action, check this post.
