WebI know E ( a X + b) = a E ( X) + b with a, b constants, so given E ( X), it's easy to solve. I also know that you can't apply that when its a nonlinear function, like in this case E ( 1 / X) ≠ 1 / E ( X), and in order to solve that, I've got to do an approximation with Taylor's. WebFeb 16, 2024 · By Moment Generating Function of Exponential Distribution, the moment generating function MX of X is given by: MX(t) = 1 1 − βt. From Variance as Expectation of Square minus Square of Expectation : var(X) = E(X2) − (E(X))2. From Moment in terms of Moment Generating Function, we also have: E(X2) = M ″ X(0)

WebApr 13, 2024 · We present a simple method to approximate the Fisher–Rao distance between multivariate normal distributions based on discretizing curves joining normal distributions and approximating the Fisher–Rao distances between successive nearby normal distributions on the curves by the square roots of their Jeffreys … WebFeb 19, 2024 · If a player scores goals at a certain rate, we can say his probability of scoring in any game is approximately totals goals / total games played. To find the expected number of games without a goal (ie. schnied, goal drought, streak) we take the exponential of the number of games, by the probability that the player wont score a goal.
