Laser speckle patterns are random variables. The PDF of the intensity Z of laser speckle is given by fZ (z) = 1/2σ^2 exp(− z/ 2σ^2) u (z) where u (z) is the unit step function. Find a maximum likelihood estimator for the parameter σ based on n independent measurements of Z.

Let X1,...,Xn be mutually independent random variables, each with pdf f(x|θ) = 2θx exp(-θx^2), for x > 0. What is the log-likelihood of θ? (a) 2θ ∏ xi exp(-θxi^2) (b) n log(2θ) + ∑ log(xi) - θ ∑ xi^2 (c) 2^n θ^n ∏ xi exp(-θ ∑ xi^2) (d) n log(2θ) + ∏ log(xi) - θ ∑ xi^2 (e) n log(2θ) + ∑ log(xi) - θ ∏ xi^2 Continuing with the example in Q1, the MLE of θ is (a) ∑ xi^2 + ∑ log(xi) / n (b) n / (∑ xi^2 + ∑ log(xi)) (c) ∑ xi^2 / n (d) n / (θ - 2 ∑ xi) (e) n / ∑ xi^2
