Hi,
I have run a couple of different ARIMA model. i want to rank the models based on RMSE or MAE.
However, i do not know how to get RMSE and MAE. the resluts show AIC and SBC.
regards
Thanks
You can easily calculate the RMSE errors and also some other errors like Mean Percentage error (MPE) by using the accuracy function.
ex:
If the name of your model is name
then RMSE is calculated as :
accuracy(name)
which will give:
ME RMSE MAE MPE MAPE MASE ACF1Training set 0.05576569 8.313739 6.227064 395.7271 576.6584 0.5128541 -0.09583192
