You may be interested to hear of some recent enhancments to the gretl GUI. These are in CVS and the snapshots for Windows and OS X. * Re-ordering of series in dataset. Up till now the only way to change the order of the series in a gretl dataset was to save the data under a different name (selecting a revised order for the series via the "store" command or the GUI dialog), then copy the new gdt file over the old one. Now you can make changes via the GUI. Select a series and either right-click and choose "Edit Attributes" (or type "e") to get the Edit Attributes dialog. This now has an "ID number" spinner which lets you reposition the variable. (But note that if you have defined named lists, or saved models, you will not be able to make a change that disturbs the order of series that are referenced by such objects.) If you then save the dataset, the new order is preserved when you reopen it. * Re-ordering of regressors in the model selection dialog. Suppose you have a list of regressors in place in the right-hand pane of the model dialog, and for reasons of presentation or comparability you want to change their order. Up till now you would have to remove the regressors from the list then refill it in the preferred order. Now you can select one or more series names and right-click to get a popup menu with Up and Down arrows. Use these to shift terms as you wish. (But note that since the constant is always automatically placed first in gretl output, this popup menu is not available when the constant is selected.) * Named lists of series. In the main window's Data menu there are two new items: "Define list" and "Select listed variables". "Define list" lets you create a named list; if more than one series is selected when you choose this item the selected series are shown as the default list-members (but you have a chance to alter this). "Select listed variables" gives you a dialog with a pop-down menu containing all currently-defined lists: if you choose one, the members of that list are automatically selected in the main window (so you can then right-click to get summary statistics, a correlation matrix, or whatever, for the listed variables). * Main window right-click menu with multiple series selected, correlation matrix option: this now presents an initial dialog with the option of imposing a uniform sample for all the pairwise correlations, in case of missing data. This corresponds to the --uniform option for the "corr" command. Allin Cottrell
