I must admit I haven't done much/any forecasting with gretl and
I sort of assumed that forecasting with VARs/VECMs was already
all set up and could be used for this problem.
Forecasting for VARs/VECMs is indeed quite advanced, but it's not
set up to handle mixed levels and differences, other than in the
specific form implied by a VECM.
