[Gretl-users] Estimation with full range of data

Hello I opened a previously saved session. When I estimate the model with OLS the estimation is done for a subset of the full range of data. Despite the fact that I tell gretl to take the full range through the menu "Sample" the estimation is always done with a subset of the data available.I've been doing it a couple of time and I always get the estimation for the same subset of data. I don't know why. Thank you for your help Raul
