Putting the results in context
As any other method, index models are subject to bias. In general, you should not have too much confidence in the results of an individual index model. Instead of relying on results from single index models, one should look at combined index models or, even better, the combined PollyVote forecast that uses forecasts from different methods, each of which draws upon different data.
Results compared to other index models
An average of recent index models has Clinton at 53.4% of the two-party vote. This value is 2.4 percentage points higher than respective numbers in the Big-issue index model.
Results compared to the combined PollyVote prediction
The latest PollyVote expects Clinton to gain 52.6% of the two-party vote. PollyVote currently predicts Clinton to gain 1.6 percentage points more compared to the results of the Big-issue model.
