Math 541 Statistical Theory II Methods of Evaluating Estimators Instructor Songfeng Zheng Let X1;X2;¢¢¢; be n iid random variables, ie, a random sample from f(xjµ), where µ is unknown An estimator of µ is a function of (only) the n random variables, ie, a statistic ^µ= r(X 1;¢¢¢;)There are several method to obtain an estimator for µ, such as the MLE,SAMPLE EXAM QUESTION 2 SOLUTION (a) Suppose that X(1) < < X(n) are the order statistics from a random sample of size n from a distribution FX with continuous density fX on RSuppose 0 < p1 < p2 < 1, and denote the quantiles of FX corresponding to p1 and p2 by xp1 and xp2 respectively Regarding xp1 and xp2 as unknown parameters, natural estimators of these quantities are X(dnp
