Dear all, 
 
For me, it is extremely embarrassing to write about this. However, I couldn't figure out a solution after several days.
 
I am running 16 Pooled Mean Group estimations and in 15 I was able to mirror the results in Eviews. In several cases, I needed to change the settings for the matrix in the last line of the following code,
 
open D:\sample.csv
setobs codes year --panel-vars
include PMG.gfn
list X = ln_rnna_cap tra_share v_g_share
modtype = 1
bundle b = PMG_setup(ln_rgdpna_cap, X, 2, , modtype)
PMG_estimate(&b, , {0;0;0},1000)
 
Most of the time, I achieve the exact results of Eviews by setting {1;0;0}.
 
Unfortunately, in one case it has been impossible and I really tried several combinations. Here I just attached a csv file with the data involved in the problem. I also attached the Eviews output and the Gretl sample script.
 
Please, if anyone of you can figure out any hint, it will be really great. Of course, I am not asking a member of the community to "iterate" for me, buy maybe anyone has a quick hint about this.
 
Very much thank you in advance,
 
Reynaldo
