st: cointegration, johans command

[Combes Stephanie <Stephanie.Combes@ensae.fr>]

Hello,

I'm trying to use the command johans for cointegration but I fail to
understand how to get the estimated cointegrated relations (it is apparently
not given as a non optional output, but I can't find which option would supply
them). I tried to get them next through the vececm command but I couldn't
either.
If someone uses regularly the command, I would be very grateful for your
help. Would you give any piece of advice for the choice of lags?

Bonus question : if cointegration rank is above 2, do I have to check that
both elasticities to long-run equations are negative in my estimated models?
I must confess that I have a hard time interpretating when there is more
than one cointegrated equation.

Thank you by advance for your time and help.
With regards,

Stephanie
