NRL Predictions for Round 1
Team Ratings for Round 1
I have decided to not give home ground advantage to the Warriors for any games played at their Australian base on the Central Coast of New South Wales. I will treat all those games as being played on neutral ground.
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.
| Current Rating | Rating at Season Start | Difference | |
|---|---|---|---|
| Storm | 14.53 | 14.53 | -0.00 |
| Roosters | 10.25 | 10.25 | 0.00 |
| Panthers | 8.88 | 8.88 | 0.00 |
| Rabbitohs | 7.73 | 7.73 | -0.00 |
| Raiders | 6.98 | 6.98 | 0.00 |
| Eels | 1.68 | 1.68 | -0.00 |
| Sharks | -0.76 | -0.76 | 0.00 |
| Warriors | -1.84 | -1.84 | 0.00 |
| Knights | -2.61 | -2.61 | -0.00 |
| Wests Tigers | -3.07 | -3.07 | -0.00 |
| Sea Eagles | -4.77 | -4.77 | -0.00 |

Nice work. 100% correct choosing the winners. The spread was off but mate, what a legend! Was looking to learn how to create a stat model to back up my personal predictions. Had the warriors in my head but no solid stats to reconfirm. In finding how to create my own model i found this handy site. Thank you so much.
