摘要
利用有限测度的广义加法公式,对取值在有限区间的n个独立同分布的随机变量的和的分布给出了一种求法.并求出了总体分布为均匀分布、截尾指数分布、截尾Γ分布情况下n个随机变量和的分布.
Consider a series random variables which are independent of each other and have identical distribution. By using the generalized addition formula of finite measures, a method of calculus is given in order to obtain distribution of the sum of those variables. Formulas of some special distribution functions, such as uniform distribution, interruption exponential distribution and interruption Gamma distribution are gotten.
