Question: Consider the AR(1) model yt = yt 1 + t with t N(0v). (a) Find the MLE of ( v) for the conditional likelihood. (b)

Consider the AR(1) model yt = yt 1 + t with t N(0v).

(a) Find the MLE of ( v) for the conditional likelihood.

(b) Find the MLE of ( v) for the unconditional likelihood (1.17).

(c) Assume that v is known. Find the MAP estimator of under a uni form prior p( ) = U( 11) for the conditional and unconditional likelihoods.
