二维连续型随机变量函数的分布密度

the density function calculation for the functions in two random variables of continuity type

利用分布函数法求二维连续型随机变量函数的分布密度是通用的方法,但这种方法在具体实施中会遇到计算上的麻烦,本文着重对使用变量变换法求二维连续型随机变量的函数的分布密度进行了探讨,并得出了若干结论。

Using the distribution function method on computation of two dimensional continuous random variable function distribution density is a common method, but this mehod in the concrete implementation will encounter trouble of calculation, this paper focuses on the use of variable transformation method for two - dimensional continuous random variable function distribution density, and swae conclusions are obtained.
