Jim Cramer breaks down what drove Monday's market action and bank stock rebound

SOLVED: For a single-parameter estimation problem, where measurements have been performed over multiple independent channels i, i = 1, 2, ..., N, find the relation between the Cramer-Rao lower bound of the joint detection, σ^2joint, and that of each individual-channel detection σ^2i.

7.38 For each of the following distributions, let X1, …, Xn be a random sample. Is therea function of θ, say g(θ), for which there exists an unbiased estimator whose varianceattains the Cramér-Rao Lower Bound? If so, find it. If not, show why not.(a) f(x|θ) = θ x^θ - 1, 0 0(b) f(x|θ) = (log(θ))/(θ - 1)θ^x, 0 1
