Selecting a random sample from a set is simple. But what about selecting a fair random sample from a set of unknown or ...

The construction of computer models of two-dimensional random surfaces and their application to the study of ejections of these surfaces are considered in the work. Conducted computer experiments ...

A new family of distributions, constructed by summing two correlated gamma random variables, is studied. First, a simple closed form expression for their density is derived. Second, the three ...
