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

Discrete differential calculus is the study of the definition, properties, and applications of the difference quotient of a function. The process of finding the difference quotient is called differentiation. Given a function defined at several points of the real line, the difference quotient at that point is a way of encoding the small-scale (i.e., from the point to the next) behavior of the function. By fin… WebHowever, this discrete function does not have the discrete analogs of the properties of the continuous function, and can lead to undesired effects, ...
