摘要:
Two examples of absolutely continuous bivariate distributions are given. The first example illustrates the fact that the sum of two random variables can be χ2, one of the variables χ2, the other variable positive but not necessarily χ2. The second example illustrates the fact that the sum of the variables can be χ2, each variable can be χ2, the degrees of freedom add up properly but the two variables need not be independent.
