But there is still another uncommon thing in JMulTi....Johansen procedure doesn't allow restrictions on beta! You can test them but you can't impose them. The good thing is that when you use gretl and JMulTi together you get a killind data machine. Fortunatelly, gretl has a great possibilitis to import and export datas, so this two softwares can be used as one. This is why I'm opting for vecm estimation in gretl with allowed imposing restrictions on beta. In general, JMulTi forum is a little bit "dead" in past few months. So, it is not so easy to reach the developers.

Thank me for annoying Markus until he gave up ;-) -sven _________________________________________________________________ Windows Live™ Messenger has arrived.
