    Method of Moments

    Question: Let X1, X2, ... , Xn be a random sample of size n from a population with pdf f(x;theta) = [3(theta - x)^2] / (theta)^3 from 0 < x < theta and zero otherwise. Use the Method of Moments to find a point estimator for theta.

    Help with unbiased estimators and efficiency

    Suppose that Y1, Y2, ..., Yn constitute a random sample from the density function f(y|t) = e^-(y-t), y>t where t is an unknown positive constant a. Find an estimator t1(hat) for t by the method of moments b. Find an estimator t2(hat) for t by the method of maximum likelihood c...
