I am trying to compare some method of forecasting on wind speed data that I have.
Validation method I saw often use RMSE and MAE. So I am planning to observe these values on different forecast method.
It is just in most paper I read the picture graph they only show curve fitted not out of sample graph. So I am kinda confused , could I really just use observation of fitted graph?
Another question if you do not mind, is there recommendation of other method that I could compare with ARIMA? Currently SVM and Holt-Winters are a candidate but, I want to see if there are other method better suited for the 1 year wind speed data that I have.
Thanks in Advance.
