论文摘要
我们使用组合论证和先前在Mosimann(1962)中获得的阶乘时刻介绍了多项式分布的中央和非中心矩的第一个通用公式。我们使用公式为所有非中心矩和第4阶的所有中心矩提供明确的表达式。这些结果在Newcomer(2008)和Newcomer等人的那些中大大扩展。 (2008年),其中非中心矩计算为4。
We present the first general formulas for the central and non-central moments of the multinomial distribution, using a combinatorial argument and the factorial moments previously obtained in Mosimann (1962). We use the formulas to give explicit expressions for all the non-central moments up to order 8 and all the central moments up to order 4. These results expand significantly on those in Newcomer (2008) and Newcomer et al. (2008), where the non-central moments were calculated up to order 4.
