摘要
对卷积公式进行推广,得到了求二维连续型随机变量线性组合分布的卷积公式,该方法在求二维连续型随机变量线性组合分布时较分布函数法更加简洁、高效,更适用于此类问题的求解。
The convolution formula was generalized in the paper, and general convolution formula which to solve two dimension continuous random variable＇ s linear combination distribution was obtained. Comparing with distribution function, the new formula is more succinctly and more efficient, which will be better for sol- ving such problems.
