Abstract:
|
Various efforts have been made to predict federal election outcomes. This talk begins with a review of the discrepancies between the real outcomes of recent Canadian federal elections and the predictions by the existing approaches such as the ones proposed by Grenier (www.threehundredeight.com) and Rosenthal (2011). We then critique the existing procedures to motivate an multi-level predictive model and its associated election prediction. We fit (train) the model with combination of the historical election outcomes with data from the Canadian Community Health Survey (CCHS) by 2011. Strategies are proposed for dealing with aggregated information, biased sampling, and spatio-temporal correlation. The fitted model is validated by the combined data after 2011 till 2015, the last Canadian federal election.
