hello
I was running arima and arfima model for forecasting index, but the residuals weren't normal, what do I do for normalization?
best regards.

hello I want to compare arima and arfima model in predicting index. in arima model because of static forecast i can compare actual data with the forecasted data. in arfima model after fracdiff and writing the equation,i can do dynamic forecast. how can i compare this with actual data? how can return...

thanks for your reply, you mean i cant do arfima model in eviews at all or static forecasting cant be done.what should i do?
should i use another software?
