The Crosstab model published an updated forecast of the election result. The model currently forecasts a major vote share of 48.7% for Clinton, and 51.3% for Trump in Arizona. In comparison, on October 26, Clinton was predicted to end up with only 48.6% of the vote.
Putting the results in context
As any other method, models are subject to bias. Thus, as a general rule, a good strategy is to not have too much confidence in the results of an individual econometric model. At the very least, one should check how a model's results compare to benchmark forecasts.
Results compared to the combined PollyVote prediction
The current PollyVote anticipates Trump to gain 51.1% of the two-party vote in Arizona. The results of the Crosstab model for Trump are thus 0.2 percentage points above the combined PollyVote in Arizona.
