[FONT=&quot]Hallo every body,[/FONT]
[FONT=&quot]I just have a typical non-stationary time series, in order to have ARIMA forecasting Model I applied the first difference d(1) to this series.[/FONT]
[FONT=&quot]After the first difference I got the result as following. Is the following series still non-stationary or stationary?[/FONT]
[FONT=&quot]what do you suggest for order of AR and Ma?[/FONT]
[FONT=&quot]Thanks in advance[/FONT]
