Abstract
Consider iid real-valued random vectors of size having iid coordinates with a general distribution function . A vector is a maximum if and only if there is no other vector in the sample which weakly dominates it in all coordinates. Let be the probability that the first vector is a maximum. The main result of the present paper is that if is growing at a slower (faster) rate than a certain factor of , then (resp. ) as . Furthermore, the factor is fully characterized as a functional of . We also study the effect of on , showing that while may be highly affected by the choice of , the phase transition is the same for all distribution functions up to a constant factor.
