不同类型随机变量和差积商的分布

The Sum,Difference,Product and Quotient Distributions of Inhomogeneous Variables

研究两种不同类型的随机变量,即离散型随机变量ξ与连续型随机变量η的和(ξ+η)、差(ξ-η)、积(ξη)、商(ξ/η)的分布,给出这些分布的密度函数.

Let η be a discrete random variable, η be a continuous random variable, the distributions of ζ-＋, ζ-η, ζη, and ζ/η are studied, and the density functions of these distributions are given respectively.
