The Lewis-Beck & Tien model is captured in the econometric models component of the PollyVote. The model currently forecasts a two-party vote share of 51.1% for Clinton, and 48.9% for Trump.
Putting the results in context
Individual models can incorporate substantial errors, and should be treated with caution. Instead of relying on results from single models, one should use combined models or, even better, the combined PollyVote forecast that incorporates forecasts from different methods, each of which draws upon different data.
Results in comparison to other econometric models
Looking at an average of econometric models, Clinton's two-party vote share is currently at 50.0%. Relative to numbers in the Lewis-Beck & Tien model Clinton's econometric model average is 1.1 percentage points lower.
Results compared to the combined PollyVote forecast
The current PollyVote foresees Clinton to gain 53.9% of the two-party vote. The results of the Lewis-Beck & Tien model for Clinton are thus 2.8 percentage points below the combined PollyVote.
