Were that particular panel no.1 or no. 5, it is straightforward. But this one is no.3 Is there a specific boolean expression to exclude that with ID=3? Simply specifying ID = 3 or ID==3 does not seem to work. Suggestions welcomed. Since you want to exclude, you probably need the inequality test. Example: open grunfeld smpl firm != 3 --restrict The indicator "firm" already exists in this dataset. In yours it seems to be "ID"? Or do Add/Panel/Unit index. cheers sven _______________________________________________ Gretl-users mailing list -- gretl-users(a)gretlml.univpm.it To unsubscribe send an email to gretl-users-leave(a)gretlml.univpm.it Website: https://gretlml.univpm.it/postorius/lists/gretl-users.gretlml.univpm.it/
