If I understood well, this is possible in JMulTi under "Subset
restrictions".Manny

thanks sven .
that's exactly what i want .
who understand what i want please describe me how can i do this.

I think Aymen means to have the same lags in each equation, but with a
"gappy" structure, for example include the first and third lags, but not
the second (everywhere). 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

Aymen,
If your lags differ in each equation, it's not really a VAR.
However
you could specify the equations separately and estimate them as a SUR
model. Have a look at the "system" command.
I hope this helps,

autoregressive
good evening
i have a problem with gretl_var.
first with the function ar_model i can specify the lags
FOR EXAMPLE: Yt= Yt-3 + Y t-2 + Yt-6 +CONST but with gretl I
CAN'T
i just enter the lag order .
HOW can i specify the lags .
my project work personalized lags please answer me .
thanks for all
