Suppose that Y; ~ N(0, 6), and we observe a sample of n observations Y], .. ., Y . Then, for an estimate , the likelihood is L(8) = II exp i=1 V216- 20 Note: . Here x is actually the number (3.14159...), not a parameter . The parameter of interest is o, not o. So when you take the derivative of the log likelihood, it is with respect to &- Question 15 Calculate the maximum likelihood estimate of o. Show all your steps
