Hi, in this question i get as far as e^beta=sumy/n ie e^beta=ybar the solution says that beta=ybar but why do we not take logs as the beta is in the exponential i thought it was beta=lnybar can someone help please? thank you
Hi Alfie It should be beta=ln ybar, it is correct in the ASET but not in the examiners report, it was a typo Thanks Andrea
