The moment generating function of Tn is Mn(s) = E(esTn) = ( r r − s)n, − ∞ < s < r. Proof. The moment generating function can also be used to derive the moments of the gamma distribution given above—recall that M ( k) n (0) = E(Tk n). NettetIn this article, we introduce a new three-parameter distribution called the extended inverse-Gompertz (EIGo) distribution. The implementation of three parameters provides a good reconstruction for some applications. The EIGo distribution can be seen as an extension of the inverted exponential, inverse Gompertz, and generalized inverted … mods für ark download
