Hi guys. I am following both bionic turtle and GARP materials and have a question about the second one. in chapter 10, question 10.18 the task is to forecast RGDPG with AR(2) model using formula yt = 1.765 + 0.319* y(t-1)+0.114*y(t-2). Fairly straightforward, but i do not understand where the got the number 2.564 from and why 2.793 is used for for t-2 period. I saw a fair amount of typos in the materials, so suspect it is in that direction, but would appreciate any help if it is not. Thank you!
