Exit poll for June 8th election: Another stunning success for statistical methods!

The election-day exit poll methods developed by Warwick Statistics professor David Firth surprised the world yet again at 10pm on election day, immediately after the polling stations closed.

The exit poll, commissioned jointly by broadcasters BBC, ITV and Sky, correctly predicted that the Conservatives would be the largest party in a hung parliament as the result of last Thursday's election. This was quite different from what had been expected by most politicians, commentators and the global financial markets — and a long way short of the increased majority that PM Theresa May had wanted when she called a snap election (three years earlier than scheduled).

Professor Firth said:

It's very pleasing that this continues to work so well — and especially pleasing that most people seem now to trust that the exit-poll prediction will usually be fairly accurate, regardless of the various pre-election opinion polls and punditry that might suggest otherwise.

Election exit poll: Not quite 'spot on' this time, but another triumph for statistical methods!

The exit-poll design and analysis methods developed by David Firth (with political scientist John Curtice from the University of Strathclyde) were used again at this week's General Election by all of the major UK broadcasters.

At 10pm on election day the on-air seats prediction (simultaneously on BBC, ITV and Sky) based on the exit poll was: Con 316, Lab 239, SNP 58, LD 10, others 27. The actual result of the election was Con 331, Lab 232, SNP 56, LD 8, others 23.

The 2015 exit-poll prediction was thus not "spot on" as it had been in 2005 and 2010. Many commentators had warned beforehand that the 2015 election would be an especially difficult one to predict. The exit-poll prediction was startlingly different from what had been indicated by commercial pre-election voting-intention polls. (e.g., see The Observer on 10 May, After the exit poll, a tsunami raged across the political map) The exit poll strongly indicated the Conservatives as largest party, and the ultimate outcome of a small Conservative majority was clearly not ruled out. This was in stark contrast to predictions from pre-election polls, which had consistently shown Conservative and Labour neck-and-neck with neither party close to an overall majority.

There were some notable public quotes, most prominent of which came from the former Liberal Democrat leader Lord Ashdown, who was interviewed soon after 10pm on the BBC:

If this exit poll is right, I will publicly eat my hat on your programme.

(He was referring to the predicted collapse of the Liberal Democrats to just 10 parliamentary seats. In the event, it turned out even worse than that for the Liberal Democrats, who won just 8 seats. Lord Ashdown failed to keep his hat-eating promise, though!)

Warwick selected as one of the founding members of the Alan Turing Institute for Data Science

The Department of Statistics at Warwick led a team of academics from the Mathematics Institute and the Departments of Computer Science and Statistics in bidding to be founding partners in establishing the Alan Turing Institute for Data Science in the UK. The Business Secretary, Vince Cable, has announced that five universities were selected to lead the Alan Turing Institute, one of which is Warwick. The four other universities are Oxford, Cambridge, UCL and Edinburgh. Warwick’s pivotal role in the Alan Turing Institute will be led by Professor Mark Girolami from the Department of Statistics.

Data Science has been an integral part of Warwick’s vision for the Mathematical Sciences. Warwick is home to the Warwick Data Science Institute and an undergraduate degree programme in Data Science, both the first of their kind in the UK.

Detailed press announcements can be found at the University of Warwick’s main site, the Business Information Portal, and EPSRC.

The Alan Turing Institute will be physically located in London’s new Knowledge Quarter.

Heather Turner to give invited course in Zurich

Dr Heather Turner, statistical consultant and currently an Associate Fellow of Warwick Statistics, has been invited to give an intensive one-day course Introduction to Generalized Nonlinear Models in Zurich on 11 May 2015. The course is based on Heather's work as a Senior Research Fellow at Warwick, which included the development of award-winning software package gnm.

Heather's work and her views on statistics, science and R development are featured in this extended interview recorded at the useR! 2014 conference in Los Angeles.
