Recursive Computation Method for Higher-order Moments about the Origin of a Kind of Discrete Distribution
YU Jing-xian · Science Technology and Engineering · 2010
Considering the complexity on calculating the moments about the origin of higher-order of variable,ni=n-1 i-1+n-1 iandini=nn-1i-1 which are two important combinational identities,are applied to the computation of higher-order moments about the origin of a kind of discrete distribution.The recursive computation formulas of higher-order moment about the origin of binomial distribution,negative binomial distribution,hypergeometric distribution are given.
