Let X and Y be two random variables such that X takes only two valoues 1 and 2. The notion of totla positivity of order two for the joint probability distribution of X and Y is discussed in this paper ...

We study methods for computing the distribution functions of bivariate compound random variables. In particular, we consider three classes of bivariate counting distributions and the corresponding ...
