Hello,

I am a fairly new GRETL user in the classroom. I am teaching an intro econometrics course where the students can use GRETL or Eviews. Everything is going well, so far. But I would like to use SVAR in a follow up course. However, I am stuck in neutral. I downloaded the SVAR package and was testing it out using the provided HANSL:

# turn extra output off

set echo off

set messages off

# open the data and do some preliminary transformations

open sw_ch14.gdt

genr infl = 400*ldiff(PUNEW)

rename LHUR unemp

list X = unemp infl

list Z = const

# load the SVAR package

include SVAR.gfn

# set up the SVAR

Mod = SVAR_setup("C", X, Z, 3)

This generates the following:

gretl version 1.9.9

Current session: 2013-03-30 02:18

# turn extra output off

? set echo off

Read datafile C:Files_ch14.gdt

periodicity: 4, maxobs: 164

observations range: 1959:1-1999:4

Listing 3 variables:

0) const 1) LHUR 2) PUNEW

Data types not conformable for operation

*** error in function SVAR_setup

> bundle ret = null

Error executing script: halting

> Mod = SVAR_setup("C", X, Z, 3)

I suspect that I installed the package wrong. How can I get it to work without the "*** error in function SVAR_setup

> bundle ret = null"?

Thanks.
