4. Estimation based on a function of the observation. Let e be a positive random variable, with known mean p and variance o?, to be estimated on the basis of a measurement X of the form X = vOW. We assume that W is independent of e with zero mean, unit variance, and known fourth moment E[W4]. Thus, the conditional mean and variance of X given O are 0 and 0, respectively, so we are essentially trying to estimate the variance of X given an observed value. (a) Find the linear LMS estimator of e based on X = x. (b) Let Y = X?. Find the linear LMS estimator of O based on Y = y.
