Stochastic ordering
open-in-new
<p>In <a href="/facts/Probability_theory/mFBn51rE">probability theory</a> and <a href="/facts/Statistics/DNPsKGYU">statistics</a>, a stochastic order quantifies the concept of one <a href="/facts/Random_variable/TwTBXnLT">random variable</a> being "bigger" than another. These are usually <a href="/facts/Partial_order/qb4a3FAX">partial orders</a>, so that one random variable A {\displaystyle A} may be neither stochastically greater than, less than, nor equal to another random variable B {\displaystyle B} . Many different orders exist, which have different applications. </p>
