II Moments of a Distribution and MGF’s 1 Moments: 1st Moment = E(X) 2nd Moment = E(X2) = Var(X) + E(X)2 = Var(X) + (1st Moment)2 Central Moments: nth central moment = E[ (X – m)n] So 1st central moment = 0 2nd central moment = Var(X) Skewness and Kurtosis: Let mn be the nth central moment of a r v X Skewness: a3 = m3 / (m2)
Moments can be calculated from the de?nition or by using so ca lled moment gen-erating function De?nition 1 13 The moment generating function (mgf) of a random variable X is a function MX: R ? [0?)given by MX(t) = EetX provided that the expectation exists for t in some neighborhood of zero More explicitly the mgf of X can be

M(?mn) we see that the odd-order moments are all zero For the even-order moments Atkin and Garvan [7] showed that the generating functions of Mk(n) are related to quasimodular forms while Bringmann et al [8] showed that the generating functions of Nk(n) are related to quasimock theta functions
crank moments of higher order 1 2 Ordinary and symmetrized rank/crank moments of higher order In general there are two types of rank/crank moments attracting broad research interest The rst type which is due to Atkin and Garvan [6] is the most natu-ral Let N(m;n) (resp M(m;n)) count the number of partitions of n whose rank
