I would like to forecast for next 2 months using 1 year data captured at monthly level.
sample of the data
- 201702 7
- 201703 1344
- 201704 1311
- 201705 2645
- 201706 8581
- 201707 7271
- 201708 11550
- 201709 11372
- 201710 7089
- 201711 10677
- 201712 9147
- 201801 2992
first column indicated month, second column indicates demand of product. I have used time series like arima, ets, ma all of them over fit. Can you suggest some basic models that may solve the problem?
Thanks
