The DeSart & Holbrook model is included in the econometric models component of the PollyVote forecast. It currently forecasts a major vote share of 42.8% for Clinton, and 57.3% for Trump in Louisiana. In comparison, on October 22 Trump was predicted to garner 57.0% of the vote.
Putting the results in context
As any other method, models are subject to bias. As a result, you should not rely too much on the results of an individual econometric model. Instead of trusting the results from single models, forecasting research recommends to rely on combined models or, even better, a combined forecast that incorporates different methods and data.
