WebThe mean of X can be found by evaluating the first derivative of the moment-generating function at t = 0. That is: μ = E ( X) = M ′ ( 0) The variance of X can be found by evaluating the first and second derivatives of the moment-generating function at t = 0. That is: σ 2 = E ( X 2) − [ E ( X)] 2 = M ″ ( 0) − [ M ′ ( 0)] 2 WebIn numerical analysis, numerical differentiation algorithms estimate the derivative of a mathematical function or function subroutine using values of the function and perhaps other knowledge about the function. Finite differences [ edit] The simplest method is to use finite difference approximations.
