[Gretl-users] Can gretl do the moving forward forecast?

Hi, Can someone take a look to see how I can program in gretl to achieve below? Below is what I wrote for one run. How to program it so that it can run in loop? setobs 12 2000:01 smpl 2000:01 2005:12 ols y const x1 x2 x3 fcast 2006:01 2006:01 --out-of-sample setobs 12 2000:02 smpl 2000:02 2006:01 ols y const x1 x2 x3 fcast 2006:02 2006:02 --out-of-sample ... (Each time to move one month forward.) Also how to store the series data generated in those runs in a way convenient for further process? Thank you for your help! Regards, Rebecca
