【Abstract】 The moment is an important concept in probability theory and has wide application. Power series type distributions include some common probability distributions. According to the characteristics of power series type distribution analytic expression, the recursive formulas of origin moment and center moment are given by the method of derivation respectively. The difficulty of calculating the higher order moment is reduced. After verification instance analysis, this method is effective for calculating the probability distribution moment of power series type distribution.更多还原
