Dear All,

My question is:

how can I estimate VECM system with "unrestricted trend" (aka "case 5")
option as a deterministic term?

As far as I know, ca.jo in urca package allows for "restricted trend"
only [vecm
<- ca.jo(data, type = "trace"/"eigen", ecdet = "trend", K = n, spec =
"transitory"/"longrun")].
Obviously, I don't have to do this in urca, so if another package gives the
possibility, please let me know too!

Thanks in advance!

Greg
