The results of state elections aren't independent. The problems that cause most errors are going to exist in multiple states and cause the errors to be correlated.
- thaumasiotes 6y agoBut something that causes the results everywhere to be off in the same direction isn't the kind of error you say "well, that's why you don't make point predictions" about. It's a factor that has a significant, predictable influence on the phenomenon you're studying; if it's not in your model, that means you screwed up when making the model. The whole point of the model is to account explicitly for such factors.
