4. Estimation based on a function of the observation. Let O be a positive random variable, with known mean and variance o?, to be estimated on the basis of a measurement X of the form X = vew. We assume that W is independent of e with zero mean, unit variance, and known fourth moment E[W]. Thus, the conditional mean and variance of X given e are 0 and 0, respectively, so we are essentially trying to estimate the variance of X given an observed value. %3D (a) Find the linear LMS estimator of e based on X = r. (b) Let Y = X². Find the linear LMS estimator of e based on Y = y.
