History of Competitions
The M Competitions have attracted great interest, from both the academic literature and among practitioners, by providing objective evidence of the most appropriate way of forecasting various variables of interest. The fourth competition, M4, ended on May 31st, 2018. Its results/findings and all related information will be published in the winter 2020 issue of the International Journal of Forecasting (Vol. 36, No. 1 https://www.sciencedirect.com/search/advanced?pub=International%20Journal%20of%20Forecasting&cid=271676&volume=36&issue=1), where the papers can be downloaded, and the Open access ones for free.
In his blog, Rob J. Hyndman said: “The “M” competitions organized by Spyros Makridakis have had an enormous influence on the field of forecasting. They focused attention on what models produced good forecasts, rather than on the mathematical properties of those models. For that, Spyros deserves congratulations for changing the landscape of forecasting research through this series of competitions.”
