While economists cloak their views in the aura of science, what they actually do is make assumptions about the world, use those assumptions to build imaginary economies (known as models), and from those models generate conclusions.
The Assumptions: That brings us to the other key factor in any predictive modelâthe assumptions that underlie it. Every model has them, and itâs important to know what they are and monitor whether they are still true. The big assumption in predictive analytics is that the future will continue to be like the past.
