Jeffreys Prior for Matrix Case In this problem we will consider a model which has a two-dimensional parameter. Then you will calculate Jeffrey's prior using the Fisher information matrix. iid Suppose that X₁,..., Xn fl N (μ, o2), where μµ and o2 are unknown. In this case, the Fisher information matrix I (0) for 0 = (μ, ²) will be a 2 x 2 matrix, where the off-diagonal entries are 0. • Find (I (0))11- • Find (I (0)) 22- • Using your answers to the previous part, determine Jeffreys prior, π (0), in terms of u and o. Express your answer in such a form that π ((1, 1)²) = 1.
