Putting the results in context
In general, however, a good strategy is to not have too much faith in the results of single econometric models, as they sometimes incorporate large errors. Rather than relying on results from single econometric models, you should consult combined econometric models or, even better, a combined forecast that relies on different methods and data.
Results in comparison to other econometric models
