Abstract
This paper gives a theorem and two corollaries of the independence of two-dimensional continuous random variables. With an example, it illustrates that the calculation of the marginal density function is not necessary while judging two-dimensional continuous random variables by this conclusion, and the independence of X and Y can be judged from the form of the joint probability density.关键词
