There is any mathematical model that has show to be better to do forecasting in the area of economic, financial, management, operations or marketing??? I was trying to do a forecast of a selling variable, and a try a lot of models. But the one that has better performanced was to cut the variable to eliminated the stationarity and then to do a moving average in every segment. A wasn´t exciting with this results because was soo simple. Then a compared this results with a model of other person and a lose, but the different was soo little that i'm not sure if that different was statistical significance.
