I am trying to forecast demand by using some predictors like promotion, price , seasonal dummies etc.
I have heard about Transfer function Models among alternatives (like UCM) and i was wondering if anyone can share material (for SAS Base) regarding the methodology, how to interpret results and diagnostics (what makes the model for the explanantory variables fit, what should i be looking after) so that i know that the model is good to use for forecasts. Preferably i would like to have examples containing multiple predictors and not only one (like in many examples on the net) so i can have a more close example to my situation.
Off course any other proposal for model techniques are more than welcomed.
Regards and thnx in advance
