Presentation Focus

Peter's website features two statistical models that provide probabilistic forecasts for the coming New Zealand election.  One is a Bayesian state space model, and the other is based on a set of generalized additive models.  Both are implemented in R in combination with the modelling language Stan, and draw on polling data and previous election results from his 'nzelect' R package.  In this talk he'll go through the reasoning and assumptions behind the two models and explore a few implementation issues, ranging from optimising code to bring convergence times to a reasonable length, to the logistics of screen-scraping Wikipedia for the latest poll results.  This talk is in Peter's personal capacity, and the analysis is not related to any employers past or present.
