Hello, i have been working on some time series data for the last couple of days which has required the use of the ARIMA function. I have been able to grasp proper use of this function on stata however my R2 and Adjusted R2 Values are not being shown in my regression table.

Please is there a command function or setting that i have to change or implement to obtain my R2 and Adjusted R2 values.
If anyone has any input please feel free to comment.Array
