Then the VAR-OLS-estimation would still apply. Vaguely I think there was a discussion about this some time back, but I don't remember the result. Of course it's still possible to specifiy this manually as a system and do OLS, but it's not very convenient. sorry, sven Am 28.04.2013 20:54, schrieb Summers, Peter: > Aymen, > > If your lags differ in each equation, it's not really a VAR.
