Probability density formula of function of two-dimension random variable

Yuejiao Wang

Abstract

Aimed at simplifying the calculation of probability density of the two-dimension random variables function,this paper introduces the use of integral transform to the calculation formulae for probability density of two-dimension random variable function to provide new method designed for solving probability density of two-dimension random variable function.This method features a more simple operation and less difficult computationl than the distribution function method.
