Predicting the UK’s snap general election

I have decided to build a model to try to predict the results of the upcoming snap general election in the UK. I'm sure there will be many people attempting this, from various perspectives and using different modelling approaches. But I have set out to develop a fairly simple (though, hopefully, reasonable) model. In the process of describing this to you, I hope to shed some light on how statisticians build predictive models.

What’s happened to the polls since the 2015 UK election?

When British Prime Minister Theresa May called a snap election for 8 June 2017, it seemed like a smart move politically. Her Conservative Party was riding high in the opinion polls, with a YouGov poll in the Times giving them 44%, a lead of 21 points over their nearest rivals, the Labour Party. Were an election to be held the next day (as surveys often suppose) May looked to be on course for a convincing win.

Queen Elizabeth II - an extreme event monarch?

In 2016, Queen Elizabeth II entered the tenth decade of her life and cemented her position as the longest-reigning British monarch, with 65 years on the throne.

The frequency of "America" in Trump's inaugural address

In “The frequency of 'America' in America” - from the October 2016 issue of Significance - we considered the increasing frequency with which the words “America” and “American” have been spoken and written by the first 44 presidents of the United States, specifically during their State of the Union (SOTU) addresses. President Obama ended his tenure with over 1.0% of all SOTU words spoken being “America” or “American”. The analysis showed that, over the lifespan of the United States, there has been a steady and exponential increase in the usage of these words, and we predicted that the next president would achieve a frequency of "America" of between 1.0% and 1.5%.

Slow-talking the inaugural

Before Donald Trump's inaugural speech on Friday, 20 January, I wondered whether he would turn the political world upside down by delivering a high-energy improvised riff in the style of his campaign rallies. But no — his speech was scripted and read verbatim as written, although it did feature several of the signature lines from his rallies, as well as the first use of the word "carnage" in a presidential inaugural.
