GDP Forecasting: Machine Learning, Linear or Autoregression?

open access: yesFrontiers in Artificial Intelligence, 2021
This paper compares the predictive power of different models to forecast the real U.S. GDP. Using quarterly data from 1976 to 2020, we find that the machine learning K-Nearest Neighbour (KNN) model captures the self-predictive ability of the U.S. GDP and
