Hello everyone, I trying to migrate from Eviews to GRETL  so perhaps this is noob question - how can we state recursive processes in GRETL? 
I wish to simulate a simple AR process for 200 periods:
yt=0.8y(yt-1)+et
where et is N(0,1)
I generate the nulldata 200 and create a random et using randgen, I try to use the ARMA functionality but it doesn't recognize the 0.8 coefficient, when I try to estimate yt I run into problems. In E-views the code is:
smpl @first @last 
series e=nrnd 
smpl @first @first 
series y = 0 
smpl @first+1 @last 
series y = .8*y(-1)+e 
Thanks in advance!
