Putting the results in context
As any other method, models are subject to bias. Therefore, as a general rule, a good strategy is to not have too much confidence in the results of an individual econometric model. Instead of relying on results from single models, the recommended strategy look at combined models or, even better, a combined forecast that includes different methods and data.
