WebIn this work, we propose and study a new family of discrete distributions. Many useful mathematical properties, such as ordinary moments, moment generating function, cumulant generating function, probability generating function, central moment, and dispersion index are derived. Some special discrete versions are presented. A certain … WebCalculation. The moment-generating function is the expectation of a function of the random variable, it can be written as: For a discrete probability mass function, () = =; For a continuous probability density function, () = (); In the general case: () = (), using the Riemann–Stieltjes integral, and where is the cumulative distribution function.This is …
