I am stuck on finding the variance of the MLE, however. I've been thinking about solving E ( X 2) = ∫ x 2 f ( x) d x and E ( X) = ∫ x f ( x) d x with the MLE as the argument, and rearranging to solve for var ( θ ^), but I'm not sure of what f ( x) would look like using the MLE. Web1. Find the MLE of θ. 2. Note that if one estimator of θ, denoted as ˜θ, satisfies E( ˜θ) = θ, then we say ˜θ is an unbiased estimator of θ, otherwise biased. Is the MLE of θ biased or unbiased?
