Re: [Gretl-users] "Data types not conformable for operation" problem using SVAR

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
