关于2个随机变量和的反例
Counter examples on the sum of two random variables
【摘要】 构造了2个反例,说明若去掉独立性条件,2个连续型随机变量的和不一定是连续型随机变量,其对应的分布函数可能是不连续函数,也可能是奇异连续函数.
【Abstract】 Two counter examples were given to show that the sum of two continuous random variables will be not necessarily a continuous random variable if the independence condition is removed.The distribution function of the sum may be discontinuous function or singular continuous function.
