[Gretl-users] VECM: Impulse response analysis for cointegrating relations

Hi gretl users, I am just doing an empirical class project on the PPP-UIP relationship. After setting up the long-run relationships and imposing (over-)identifying restrictions on beta, I want to conduct an impulse-response analysis on the cointegrating relationships in order to check how long it needs the long-run relationships to get back to its equilibrium. Is this possible in gretl? Or has anybody a script for this or a similar problem? Thank you. Artur
