What is positive integer

[fitria]

Hi, there
i have a problem and i need your help.
i wanna know the lag optimum for my VAR model.
So, i write this into eviews program:

var test.ls 1 2 var1 var2
show test.laglen (12, vname=v1)

but, it didn't work and it said
"Lag length to test must be a positive integer. in "SHOW TEST.LAGLEN (12, VNAME=V1)""
so, what is that mean?and what should i do?
thank you so much.

You have a space between laglen and its options. Try:

Code: Select all

var test.ls 1 2 var1 var2 show test.laglen(12, vname=v1)
