For a nonnegative random variable Y with finite nonzero mean µ, we say that Y^s has the Y-size bias distribution if E[Y f (Y)] = µEf [(Y^s)] for all smooth f . If a bounded size biased coupling for Y exists, that is, if Y can be coupled to Y^s having the Y -size bias distribution such that for some constant C we have |Y^s − Y | ≤ C almost surely, then Y satisfies...
