Please send your data and we will analyze it and post the model and results here.

Make sure you include the beginning date of the data, country of origin so we can provide dummy variables to account for the lead, contemporaneous and lag effects around holidays.

I was doing forecasting how demand for cash withdrawal per day and I have a problem on the result in forecasts data. The MAPE of model already has a small value (11-20%) and all the lag is independent in the model. but, i recognize residual normality was not achieved. can you give me directions how to decide the effective replenishment period in accordance with the forecast data held? I am really waiting for your answer sir.. thank you .. hello Sir…
