Abstract

We establish a necessary and sufficient condition for the quantile process based on iid sampling to converge in distribution in L1(0,1)L^1(0,1). The condition is that the quantile function is locally absolutely continuous and satisfies a slight strengthening of square integrability. If the quantile process converges in distribution then it may be approximated using the bootstrap.
