The Crosstab model released an updated prediction of the election outcome. According to the model, Clinton will achieve 47.7% of the two-party vote share in Arizona, whereas Trump will win 52.3%. In comparison, on November 7 Trump was predicted to collect 51.9% of the vote.
Putting the results in context
As any other method, models are subject to bias. Thus, as a general rule, you should not be too confident the results of an individual econometric model. Instead of trusting the results from single models, the best practice is to use combined models or, even better, a combined forecast that draws upon forecasts from different methods, each of which draws upon different data.
