The Jerome model is included in the econometric models component of the combined PollyVote forecast. According to the model, Clinton will obtain 43.0% of the two-party vote share in South Dakota, while Trump will win 57.0%. In comparison, on August 16, Clinton was predicted to end up with 57.0% of the vote.
Putting the results in context
Single models often contain large biases, and should be interpreted with caution. Rather than trusting the results from single models, the best practice scientific advice is to look at combined models or, even better, the combined PollyVote forecast that uses forecasts from different methods, each of which draws upon different data.
The Jerome model in comparison with PollyVote's forecast
