How Does Predictive Analytics Work?
As any fortune-teller will assure you, predicting the future is an art as well as a science. And that truism applies as much to business decisions as to any other aspect of life. So on the one hand we can say that predictive analytics is a branch of statistics in which information extrapolated from historical data is applied to the projection of future conditions. That’s the science side.
On the other hand, we can say that predictive analytics is using information you do have to compensate for information you don’t have (yet), in order to make better business decisions. That’s the artful part, and it can depend as much on intuition and imagination as on algorithms.
Bringing the two sides together successfully is “what’s new” in the practice of predictive analytics.
