Hello, Could someone tell me please how can I find out which starting values has R used for the simulation? I have AR(1) model: y(t)=0.2*y(t-1)+0.2*y(t-2) + e(t) (e(t) is distributed according standard normal distribution) I need y(0) (or y(t-1), then t=1) values for my following calculations (it is very important parameter). Should I assume that y(0)=mean(yt) or set y(0)=0? How to find out, which values R uses for y(0), y(-1) and so on? Thank you very much for the answer in advance!
