Hello,
In order to do a future forecast based on my past Time Series data sets
(salespricesproduct1, salespricesproduct2, etc..), I used arima() functions
with different parameter combinations which give the smallest AIC. I also
used auto.arima() which finds the parameters with the smallest AICs. But
unfortuanetly I could not get satisfactory forecast() results, even
sometimes catastrophic results which made me very disappointed.
Note that, I basically use plot(forecast(auto.arima(invecTS), 24)) statement
to construct model with arima, forecast 24 future values & plot the results.
Could you suggest me better forecasting methods that I can apply in R ?
Thanks, best regards..
Ozcan
