smat parameter in impulse function generates zeros in matrix

Postby fboralli » Wed Aug 12, 2015 12:57 pm

The smat parameter sometimes creates a matrix with a column full of zeroes in it. in the table, the real data is shown.

version: Eviews 9 - jun 24 2015 build
The code below reproduces this problem.

Code: Select all

wfcreate q 2000 2015
series a1=nrnd
series a2=nrnd
series a3=nrnd
var v.LS 1 2 a1 a2 a3
v.impulse(16,t,smat=tt) a1 a2 @ a3


The table shown from the impulse and tt matrix should be equal, but they are not.
