Maximum likelihood and map estimation (4 pts): of the exponential distribution p(x) = λ exp(−λx) , x ≥ 0 0, , x < 0 (1) from a set of measurements of x, specified by xn; i = 1, 2, n. assume that the prior is given by p(λ) = α exp(−αλ) , λ ≥ 0 0, , λ < 0 (2) (a) determine the expression for the maximum likelihood estimate of the parameter λ from xn; i = 1, 2, n. (b) determine the expression for the map estimate of the parameter λ from xn; i = 1, 2, n.
