The Presidential election forecasting models I’ve been following this election cycle are all pointing toward a Clinton victory. Now we have to wait and see.

- Trump to win the popular vote, no electoral college prediction
- This model does not use state-level information or the electoral college (see my blog post here). It appears to be a better mid-term or long-term forecasting model.
Why don’t all of these models agree? A few articles I’ve read lately about forecasting models and polling:
- Andrew Gelman: Different election forecasts not so different.
- Don’t be fooled by Trump’s bounce. “What seems like a big change in public opinion turns out to be little more than changes in people’s inclination to respond to polls“
- FiveThirtyEight: Why Our Model Is More Bullish Than Others On Trump. Covariances are crucial.
- Is 99% a reasonable win probability? Sam Wang: Yes.
- Me: “Your model is only as good as the inputs you give it”
- Nate Silver is unskewing polls — all of them — in Trump’s direction
- Which forecasts are true? Are win probabilities even defensible?
