The DeSart & Holbrook model provided an updated prediction of the election result. The model currently predicts a two-party vote share of 44.6% for Clinton, and 55.4% for Trump in South Carolina. In comparison, on October 29 Trump was still predicted to obtain 55.7% of the vote.
Putting the results in context
As any other method, models are subject to bias. In general, you should not have too much faith in the results of an individual econometric model. Rather, one should check how a model's results compare to benchmark forecasts.
