If we think of W 1 as the number of trials we have to make to get the first success, and then W 2 the number of further trials to the second success, and so on, we can see that X = W 1 W 2 W r, and that the W i are independent and geometric random variables So EX = r/p, and Var(X) = r(1−p)/p2 5 Poisson random variables.

In this *improvised* video, I rigorously prove some properties of the exponential function, namely that e^(xy) = e^x e^y, e^x = 1/e^x and e^ax = (e^x)^aThe. Break at uniformly chosen point Y • Conditional expectation break again at uniformly chosen point X.

Ybg(T(Y)) = E Y bg(Y)2 −g(θ)2 Consequently, we can show that ET(Y) h eg(T(Y)) 2 i = ET(Y) E Y T(Y)bg(Y) (c) ≤ ET(Y) E Y T(Y)bg(Y) 2 (d) = E Y bg(Y)2, where (c) holds because of Jensen’s inequality and (d) is the result of the iterated expectation Equality. It crosses the yaxis at y = 1, and then decays at slower and slower rates The Natural Log The natural log is the logarithm whose base is e The two functions, the natural log and the exponential e, are inverses of each other In other words, saying y = Lnx is the same as e^y = x Look at the plot of y = Lnx.

Ii) Var(E(YX) = E(E(YX) E(E(YX))2) = E(E(YX) (E(Y)2), which is a weighted average of E(YX) (E(Y)2 Thus, (***) says that Var(Y) is a weighted mean of Var(YX) plus a weighted mean of E(YX) (E(Y)2 (and is a weighted mean of Var(YX) if and only if all conditional expected values E(YX) are equal to the marginal expected. I think that if you manage to state your question precisely, the answer will be E( g(X,Y)), but you haven't defined the meaning of "best" in your original post and to say a random result is "closer" to something has no specific meaning.
