摘要

给出了矩产生函数的两个不足，并举例说明。许多分布没有矩生成函数，但每个分布都有一个独特的特征函数。使用特征函数优于矩生成函数。关键词:矩生成函数;特征函数;全球数学科学Vol. 31 (2004): 23-26

SOME DEFICIENCIES IN USING MOMENT GENERATING FUNCTIONS

Two deficiencies in using moment-generating functions are given and illustrated with examples. Many distributions do not have moment generating functions, but every distribution has a unique characteristic function. The use of characteristic functions is preferred to moment-generating functions. KEY WORDS: Moment-generating functions, Characteristic functions. Global Jnl of Mathematical Sciences Vol. 31) 2004: 23-26
