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!
