Dear All, when running mode check it can happen that, for some parameter values, the model reaches some unit root boundary for which no sufficient information in the data is available. This implies an error message from the DKF routine which and the execution breaks. Shall I put a try-catch trap in mode_check to fix this ? best wishes Marco -- Marco Ratto, Euro-area Economy Modelling Centre (http://eemc.jrc.ec.europa.eu), Joint Research Centre The European Commission, TP 361, 21027 ISPRA(VA), ITALY Tel: +39 0332 78 5639 Fax: +39 0332 78 5733 marco.ratto@jrc.ec.europa.eu
