WebFeb 27, 2014 · The first derivative is f ′ (x) = ex − 1 − 1 and the second derivative is f ″ (x) = ex − 1. f is convex everywhere because f ″ (x) > 0, and has a minimum at x = 1. Therefore x ≤ ex − 1 for all x, and the equation is only equal when x = 1. Using this inequality we get. x1 a x2 a⋯xn a ≤ ex1 a − 1ex2 a − 1⋯exn a − 1. WebApr 23, 2024 · An estimator of λ that achieves the Cramér-Rao lower bound must be a uniformly minimum variance unbiased estimator (UMVUE) of λ. Equality holds in the previous theorem, and hence h(X) is an UMVUE, if and only if there exists a function u(θ) such that (with probability 1) h(X) = λ(θ) + u(θ)L1(X, θ) Proof.
