Hi all, I am constructing a forecasting model for auto sales with predictors like advertising spend and macroeconomic conditions. But, I know that auto sales have both month-to-month and seasonal trend. What is the best way to model this while accounting for the trend and seasonality?
Can I do this? Y(t) = Y(t-1) + Y(t-12) + predictor1... + e If not, what would you suggest? . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
