The DeSart & Holbrook model provided an updated forecast of the election outcome. According to the model, Clinton will garner 49.2% of the two-party vote share in Arizona, whereas Trump will end up with 50.8%. In comparison, on October 24, Clinton was predicted to collect 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, you should not have too much faith in the results of a single econometric model. Instead of relying on results from single models, we recommend to look at combined models or, even better, a combined forecast that relies on forecasts from different methods, each of which draws upon different data.
