The Method to Solve the Probability Density of Function of n-dimensional Random Variable
Abstract: In this article by generalizing the method to solve the probability density of function of two-dimensional random variable, we have obtained the method to solve the probability density of function of n-dimensional random variable ,and illustrated the method to solve the probability density of two familiar functions of n-dimensional random variable.
Keywords: function of random variable; distribution function; probability density
