You can't actually estimate Z since Z is a random variable and not a parameter you need to be careful about using estimation in this context Z is a random variable, so if you wanted to get the population mean of Z then you calculate E Z = E g (X,Y) Remember that estimation concerns estimating something that is essentially fixed, like mu2 v K e _ ^ m j Z a e b q Z l g Z m q g h h h k g h \ i j h _ d l u, b f _ x s b g Z m q g h h h h k g h \ Z g b y « G Z m q g h h h k g h \ i j _ ^ k l ZE g(X) ≥ g( EX ) Source Wolfram MathWorld a) Proof Let g(X) be −√$, for all positive real numbers g(x) is a convex function as seen by the graph to the right Since g(X) satisfies the requirements for Jensen's inequality, we can use it to directly prove the inequality
