We compare predictions for the outcome of Premier League season 2018/19. Included are only popular sites and those who have a web page for reference of the prediction and published before 10.08.2018. Eventually, at the end of the season, we compare all predictions like as it was done for the Bundesliga 2017/18.

### Sites / Institutes

The following 28 sites or institutes have published a prediction or rankings:

Not all predictions are really predictions but rankings based upon results, market value, and other sophisticated models. Those are included as references. Some of them like Goalimpact or Club Soccer Index are rankings, but based on their models a prediction was published.

Shown are the average prediction as bars together with standard deviation as error bars in grey. The colored points mark the single predictions of the above mentioned sites. Squares mark those predictions which are based on algorithms.

### Comparison of predictions

Let us give a first impression of the average predictions and standings on match day 8. This shown in the chart below. The red circles mark the standings after match day 8. It is yet not meaningful to compare the single predictions, this will be done around match day 12.

For a better comparison we use the difference: $d(m):=\mathsf{rg}_{p}(m)-\mathsf{rg}_{8}(m)$ with $\mathsf{rg}_{p}(m)$ as the average prediction rank of team $m$ and $\mathsf{rg}_{8}(m)$ the rank of team $m$ after match day 8. This deviation from prediction, is a kind of measure, how well they have done! The larger $d$ the better they have performed, negativ $d$ means they have under performed, compared to the predictions. Sorting all teams accordingly from high $d$ to small $d$ is shown in the chart below.

On top are those teams which have over performed and on the bottom those which have under performed. The $+$-signs mark the predictions, compared to the actual standing, together with standard deviations (error), already shown in the chart before. To judge whether it is really over- or under performed so far, those errors must be taken into account. All teams which are placed within this error bars, i.e. from 7.-17. place, are roughly in the rang one could expect.

So, the positive surprising teams are really Bournemouth, Watford and Wolverhampton. The really disappointing team is ManU. West Ham United and Newcastle have large error bars, in so far, despite the large deviations the rank compared to prediction is not that surprising.

The overall deviation of all predictions is best measured by the mean absolut error: $$mae := \frac{1}{20}\sum_{m=1}^{20} \Big| \mathsf{rg}_{p}(m)-\mathsf{rg}_{8}(m)\Big| = 2.87.$$ This value is in full agreement to what one would expect after match day 8 (see the discussion here).

### Conclusion

Will be done at the end of season!
