Analysing trends using Big Data has the potential to improve the accuracy of economic forecasts.
"Properly used, new data sources have the potential to revolutionise economic forecasts. In the past, predictions have had to extrapolate from a few unreliable data points. In the age of Big Data, the challenge will lie in carefully filtering and analysing large amounts of information. It will not be enough simply to gather data; in order to yield meaningful predictions, the data must be placed in an analytical framework."
