Hi, there are two behaviors of gretl I am not particularly comfort with. 1) When an open dataset is "Saved as..." with a different name (sometimes subsampled), gretl does not change anymore to the new file, but keeps on working on the old file. Example: I open dI.gdt. If I make some changes to this dataset and save it as a new file with the name dII.gdt, gretl does not automatically move to dII.gdt but it keeps on working on dI.gdt. Is this an intended behavior or a bug? I find it quite annoying as most of the time when I save the dataset in a new file I want that gretl switches automatically to it. 2) I found the possibility to automatically create interaction variables with the command "^" very useful. There is nonetheless one effect of the command that is annoying: when you use (dummy) variables in the command that are grouped together, some of the new interactions variables are placed in the same group. Here is an example: I have a panel of firms in different regions. I want to create region-time dummies. genr timedum creates the time dummies and group them together in the list of variables, and that's fine I have a categorical variable called "reg". The following commands work as expected and create the region-time dummies I need: list dt = dt_* list H = reg ^ dt i.e. dt_1_reg_1,...,dt_1_reg_20,dt_2_reg_1,... The only problem with the result is that gretl puts all the variables dt_#_reg_#, EXCEPT dt_1_reg_#, in the same group of dt_# What I would expect is that: - all the new variables are grouped together in a new group, or - all the new variables are placed in the time-dummies group, or - the new variables are not placed in any group... I know these are only minor issues, but since the new release is coming I thought this is the right moment to "ask" ;-) Bye Giuseppe
