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. WebMar 21, 2024 · Branch and bound is an algorithm design paradigm which is generally used for solving combinatorial optimization problems. These problems are typically exponential in terms of time complexity and may require exploring all possible permutations in worst case. The Branch and Bound Algorithm technique solves these problems relatively quickly. WebConfidence level is 80%. Mean is 20. Sample size is 15. Standard Deviation is 12.
