Webbsince all the Tt have all the same distribution and therefore the same mgf. We use the mgffor an exponential random variable with rate Ato get A n MTI+Tz+·+Tn(t) = (--). A - t … From the definition of the Gamma distribution, X has probability density function: 1. fX(x)=βαxα−1e−βxΓ(α) From the definition of a moment generating function: 1. MX(t)=E(etX)=∫∞0etxfX(x)dx First take tβ. We have that … Visa mer Let X∼Γ(α,β) for some α,β>0, where Γ is the Gamma distribution. Then the moment generating function of Xis given by: 1. MX(t)={(1−tβ)−αt
