Hi, it's not totally clear to me what the question is. The subject says dynamic panel, but the equation does not look like a panel model. For example, no unit/group index i. So please be more specific on what you have actually estimated, maybe also with some gretl output. thanks 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/
