Bio-index model: Clinton is in the lead
The Bio-index model provided an updated prediction of the election outcome. It currently predicts a two-party vote share of 58.8% for Clinton, and 41.2% for Trump.
Putting the results in context
As any other method, index models are subject to bias. In general, you should not put too much trust in the results of a single index model. At the very least, one should examine how a index model's results compare to benchmark forecasts.
Results vs. other index models
Clinton currently achieves 53.9% of the major two-party vote in an average of recent index models. If we look at an average of index models, Clinton's two-party vote share is currently at 53.9%. This value is 4.9 percentage points lower than corresponding numbers in the Bio-index index model.
Comparison to the combined PollyVote
The latest PollyVote anticipates Clinton to gain 53.7% of the two-party vote. The results of the Bio-index model for Clinton are thus 5.1 percentage points above the combined PollyVote.
