I am currently in the final stages of putting together my GE2017 Forecast Model. The model will predict overall seat numbers (not vote shares).
Information on the methodology is up and available on this page.
The forecast will be updated with each new poll, which will be accompanied by a Blog post and a graph tracking the forecast across the election campaign.
This is my first attempt at forecasting, so I am very excited to see how it goes and welcome all comments and criticism on both the model and presentation.
