please note - the name of your prediction model will be published on the Betfair website, and will be visible to members of the public. Please bare this in mind when naming your model.  Offensive names will not be published. 

submissions must be in a csv format; and
only one (1) prediction model will be accepted per Competition Entrant.
The metric used to determine the winner will be the Mean Squared Error over all predictions, based on the actual Brownlow votes received compared to predicted Brownlow Votes received. For example, the Betfair Data Scientists' Brownlow Model predicted Tom Mitchell to poll votes last season, while he only actually polled 28. Thus, the Squared Error for this individual prediction was . On the other hand, if our model had correctly predicted votes, the Squared Error would have been . The winner of the datathon will be the participant with the lowest Mean Squared Error over predictions for every player to poll.

The winner will be the competitor with the lowest sum of mean squared error over all player predictions. It is important that answers are submitted in the format that is provided in ‘Betfair Brownlow Datathon Submission.csv’. 
We will assume 0 predicted votes for any missing values. For example, if someone doesn’t provide a prediction for ‘P Dangerfield’ we will assume they predict 0, and mean squared error will be calculated accordingly.
Winners will be announced via email and on the Betfair website after the Competition concludes on or around 24 September 2019.

The Competition Prizes will be distributed soon after the announcement of the winners.
