Executing xtbond2 command using Innovation Drivers in Developing Countries paper

[Yassmine Hassanin]

I'm running the xtbond2 command using the data from the attached paper entitled " Innovation Drivers in Developing Countries paper".
N= 24
T=6
xtabond2 linn l.linn lins lfdi lent lgdpg lhc i.year, ///
gmm(L2.l.linn lgdpg lhc) iv(lins lent lfdi i.year) twostep robust small

I need to know what the problem is with the above command, I don't get the same results as the paper.
