Stochastic order
A stochastic order is an order on probability measures induced by a given order on the underlying space. Since there are many different ways to extend the order from the base space to probability distributions on the space, there are many different stochastic orders. Some authors speak of a “usual stochastic order,” under which one random variable is less than or equal to another whenever the corresponding survival functions are.
