England will take on South Africa in the 2019 Rugby World Cup final this weekend and I am predicting a win for England by 1 to 6 points. In other words, it will be close and exciting!
After 43 matches with 37 correctly predicted, the stage is set for an epic final between England & South Africa to settle the 2019 Rugby World Cup (Men’s). Ahead of making a prediction for that match, I have examined my model in depth and in this post I explore whether or not the model needs to be adjusted.
It’s the quarter finals tomorrow and it’s time for me to predict the outcomes using World Rugby’s rankings. Although I got 33 out of 37 matches right in the pool stages, the 4 errors are enough to change my prediction of who will win.
Augustin Pichot, vice-president of World Rugby, may not like its ranking system but ahead of the 2019 Rugby World Cup (Men’s), I have been able to use rankings to correctly predict 80% of international matches since 2017. For the world cup that starts this week, I used a dynamic ranking model to predict all matches and it shows that 4 countries cannot be separated for the trophy so we are in for some very exciting matches!
The city of Bath is among a number of cities in the UK tasked with reducing Nitrogen Oxide (NOx) emissions. NOx pollution is thought to contribute to poor health and the government has required clean air plans from the relevant local authorities to be in place before 2021. I had no idea that this would result in my statistical expertise being needed to answer a political row over the BathBreathes2021 plans to charge cars driving into Bath and you can read my report to see what my answer was!
Here is my forecast for the election that was not supposed to be happening in the UK. The Brexit Party is well on course to be the largest party and could even set the record for the best ever vote share by a party in the d’Hondt era of EU elections in the UK. At the same time, the Liberal Democrats have the possibility of beating both the Conservatives and Labour parties in a UK-wide election for the first time since 1906.
In a week’s time, Americans will go to the polls for what is known as the mid-term elections. Inevitably, the results will lead to much speculation on what it means for Donald Trump’s chances of re-election in 2020. However, I will be surprised if many commentators will look to history as a guide to 2020 and so I will fill in this gap with the help of fun 10 question quiz about US presidents.
As I write this, a plethora of economic forecasts are making the rounds in the news in the UK. In all cases, the forecasters have failed to publish their track record and these days, I will not pay attention to what they say unless their forecasts are accompanied by a track record. But, how does one go about presenting a forecasting track record to prove that one has forecasting skill? To demonstrate, I will analyse how well opinion polls have predicted General Elections in the UK and measure their track record. I must confess I was surprised at what I found out and I would urge all opinion pollsters to take note of my results.
With only 3 or 4 games to go for the teams of the Premier League, most of the season’s excitement has dissipated. Man City have wrapped up the title, the top 7 who will be playing in Europe next season is more or less settled and the former 10-team dogfight for relegation has resolved itself with a 4 point gap between the bottom 3 and the rest. Probably, the only remaining uncertainties are who will take 4th place (Spurs or Chelsea) and will Southampton escape relegation at the expense of Swansea?
The last 3 general elections have seen some significant polling errors. In 2010, the Lib Dems were significantly overestimated, in 2015 the Conservatives were underestimated and last year saw the largest ever underestimate in the Labour vote. Whilst these errors suggest that the polling industry is struggling with general elections these days, a natural question to ask is “are all pollsters equally bad or are some better than others?”
