A Question for Sports Prediction Followers

By

I have been a bit shocked by the number of hits I have got for my AFL predictions. I never advertised that I would predict the AFL this year, just said at one stage last year that I might.

For the first week of AFL I got about 40 percent more hits on the AFL predictions compared to the Super Rugby (the next most hits of that week’s predictions). I thought it might be due to posting the AFL predictions first, so this week I posted the AFL predictions last, and currently there are nearly twice as many hits for the AFL as for Super Rugby. The NRL predictions have been popular for some time and have many more hits.

I would be interested in hearing how anybody who is interested in the AFL predictions came across them because I seriously thought I would initially just get a trickle of interest since my other predictions are for rugby or rugby league.

AFL Predictions for Week 1

By

Team Ratings for Week 1

So this is new. The methodology is the same, but there are a few quirks when it comes to home ground advantage. I have used the listed home grounds in making decisions, but it is a lot more problematic. Think for example Collingwood versus St Kilda Saints played at Marvel Stadium. Should I give the Saints home ground advantage? I do. Also should home ground advantage be the same for all teams and locations. I have done that, but in future may allocate different home ground advantage for teams in the same city compared to teams playing a team from a different state or city.

You may also note that Collingwood’s rating is less than the Lions. That is how the numbers played out. I am actually fairly happy with it statistically given the result of the Grand Final (Collingwood by 4 points) which given the home ground advantage is pretty close.

Note that I am a long-time Collingwood supporter, but as is the case with all my predictions I try and make them as objective as possible, using a simple statistical method.

The basic method is described on my Department home page.
Here are the team ratings prior to this week’s games, along with the ratings at the start of the season.

Brisbane Lions 17.47 17.47 -0.00
