A random variable that can take only a certain specified set of individual possible values-for example, the positive integers 1, 2, 3, . . . For example, stock prices are discrete random variables, ...

In this article we construct an upper prediction limit for the arithmetic mean of a future sample from a lognormal distribution. First, we present three approximate distributions for the total of the ...
