We now know the answer to who will win the 2018 6 Nations Championship. Ireland won the title with a match to spare after England failure against France resulted in my second forecasting error of the championship. There is still much to play for though in the last week with the main question being whether England do to Ireland what Ireland did to England last year and stop them from winning a Grand Slam. Whilst I am cheering on England, it is St. Patricks Day and I do have some Irish blood in me so part of me does wish Ireland well.
Be careful of what you wish for! Two weeks ago, I said I was hoping for an error in my predictions based on World Rugby’s rankings and I finally got one and it was Scotland overturning my team England …
After two weeks of the 2018 6 Nations, all 6 of my match predictions have been correct. Whilst this might be vindication of the World Rugby ranking model, the last thing we want in sport is a perfect prediction model otherwise what’s the point? Where would be the excitement of watching sport live? So I am hoping for an incorrect prediction soon …
The 2018 6 Nations is underway and all of my predictions for week 1 turned out to be correct (just!) with the help of an amazing drop goal drop goal by Johnny Sexton. This means that out of 37 matches I have used rankings to make predictions, 30 have been correct.
The 2018 6 Nations begins tomorrow and fans will be looking forward to a feast of rugby for the next two months. As always, pundits galore are making their predictions and the one thing we can count on is that some will have egg on their faces by the time it is over. In 2017, I used World Rugby’s Rankings to predict who would win each match in the 6 Nations and the Autumn Internationals and these predictions worked out well with 12 out of 15 6 Nations games and 15 out of the 19 Autumn International matches involving 6 Nations teams correctly called.
The third round of the Autumn Internationals take place this weekend and for nearly all nations that will be the end of the action. For the last two weeks, I used World Rugby’s Rankings to predict who will win and to set expectations for each nation for the whole series and my predictions have worked out well with 11 out of the 12 matches involving 6 Nations teams correctly called. This performance is consistent with a similar set of predictions I made for the 2017 6 Nations where I correctly called 12 out of 15 games.
The second round of the Autumn Internationals take place tomorrow and some tasty matches await us. Last week, I used World Rugby’s Rankings to predict who will win and to set expectations for each nation for the whole series and my predictions got off to a good start with 5 out of the 6 matches correctly called. This performance is consistent with a similar set of predictions I made for the 2017 6 Nations where I correctly called 12 out of 15 games.
It’s November again and for rugby fans, it means the Autumn Internationals are on us again. The nations of Europe welcome teams from all over the world for the next 3 or 4 weeks to test each other and find out where they stand. Ahead of the first round of matches, I have used World Rugby’s Rankings to predict who will win and to set expectations for each nation.
Earlier this year, I made a similar set of predictions for the 2017 6 Nations and correctly called 12 out of 15 games. The prediction model is explained in one of my 6 Nations post but World Rugby’s goal is that rankings can be used as a predictive tool. The idea is to take each team’s current ranking and add 3 points to teams playing at home. Whoever has the higher ranking is then expected to win but clearly the closer the rankings, the closer the game is expected to be. [Read more…]
Ahead of the 2017 general election, I predicted that the opinion polls would be wrong again and that the Conservatives lead over Labour would be underestimated by 2.6%. I based this on data provided by Mark Pack who has systematically recorded every opinion poll published since 1945. In the event, I was right that the polls would be wrong but instead of an error favouring the Conservatives, the polls recorded the largest ever underestimate of the Labour vote. As a result, election forecasters were blindsided yet again and the result was a hung parliament which few saw coming.
My official prediction using my Final Election Model is that the Conservatives will make a net gain of 45 seats resulting in a working majority of 105 seats.
My forecast uses data from my latest UK Opinion Poll Tracker and it is worth reading that post in conjunction with this post. At the bottom of this post is a spreadsheet containing my prediction for each seat. I am basing all figures in this forecast on the assumption that Conservatives will have a 9.5% lead over Labour on June 8th. I arrive at that figure by taking the current CON-LAB lead of 7% in the latest polls and adding an expected 2.5% underestimate in the Conservative lead over Labour based on my analysis of historical polling errors. A knock-on effect of this assumption is that I expect turnout to be 2pts higher at 68%.
