The Jerome model provided an updated prediction of the election result. It currently predicts a major vote share of 47.2% for Clinton, and 52.8% for Trump in Missouri. In comparison, on October 12, Clinton was predicted to win 47.4% of the vote.
Putting the results in context
As any other method, models are subject to bias. In general, one should not have too much faith in the results of a single econometric model. Rather, one should check how a model's results compare to benchmark forecasts.
Results compared to the combined PollyVote prediction
The most recent PollyVote predicts Trump to gain 53.6% of the two-party vote in Missouri. The results of the Jerome model for Trump are thus 0.8 percentage points below the combined PollyVote in Missouri.
