Re: [Gretl-users] A critical bug and a feature request

I think it is far from being ideal. My understanding of the concept of a session based work model is one where the users are able to estimate different models and later revisit them and to all sorts of comparisons and tests. There is little advantage of saving a model if the user will not be able to perform any tests, draw and graphs or save the fitted values etc. Currently, what gretl wants is the user to manually return back to the original subsample before performing such operations but this may not be even possibe as in the case of models based on a random subsample. Plus, I notice that the "Modify Model..." function under the Edit menu is not affected by this behavior. So if one open a model, say using the full range, and if the data is currently subsampled, after modifying the model by adding or subtracting various variables, what he gets will be a model based on a different subsample. The current situation can also be annoying because, OK, say I opened a model using a different subsample and tried to run a test. Gretl warns me that the model is subsampled differently and makes the Tests and Graphs menu ghosted. (Why are not the menus ghosted as soon as I open the model window is a different question here.) So I go ahead and manually adjust the subsample but what happens now is that those menus are still ghosted so I need to first close the window and reopen it just because they will not be ghosted anymore. In conclusion, I have a suggestion: Could you please make it such that whenever a model is saved as an icon, gretl internally saves the observation numbers of the subsample as a vector? This will make it possible that when the user opens a saved model or activates an open model window, gretl first checks whether the current subsample matches with those of the model and opens up a dialog box asking if the user wants to return to the subsample used by the model. If the user say "yes" the subsample is automatically adjusted. If the user says "no," then the Tests and Graphs menus are diasabled along with the "Modify model" option. Could you please consider this?
