Statistics in the public eye: the case of predicting election outcome

Prof. Simon Jackman
the United States Studies Centre, the University of Sydney

Abstract
Predictive models of election outcomes – relying chiefly on published opinion polls – have been a leading example of statistical methods finding their way into media and popular discourse. After early successes, these models have been at the heart of “polling misses” in recent years across elections in the USA, Australia and the UK.

Professor Jackman will examine these successes and failures, detailing the statistical models used to temporally aggregate and smooth poll-based estimates of voting intentions - a form of Hidden Markov Model.

Professor Jackman will also discuss (a) generalisations and extensions of the model including estimating trends and discontinuities in the evolution of public opinion over election campaigns, spatial smoothing for multi-jurisdiction elections (e.g., parliamentary elections or the US Electoral College), (b) ex-post estimation of pollster biases and their causes, and (c) detecting under-dispersion or “herding” of published poll results. Examples will include recent Australian federal elections and US presidential elections. These examples hold important lessons for statisticians whose work is destined for consumption by journalists and the lay public.
