For example four moments and four linear combinations under general conditions (specified later) determine the distribution of n = 56 independent random variables, but not of 57.

This paper is concerned with the determination of tight lower and upper bounds on the expectation of a convex function of a random variable. The classic bounds are those of Jensen and ...

A random variable is one whose value is unknown or a function that assigns values to each of an experiment’s outcomes. A random variable can be discrete or continuous.
