Thank you very much for your answers,you are all very kind!Excuse me, can I make another question about time series? When I use arimaId or best.arima function in package forecast, I can't insert regressors, I can insert them only when I make predictions.. But isn't the model influenced by regressors (for example sales are influenced by presence of promotion)? What can I do? Do I have to clean the data by regressors effect before using arimaId or can I use the original data? Thank you very much, I hope to receive your answer.. Giusy
