I may have missed the point here but isn't this an obvious case for using the bootstrap. A paper by Mallows, the exact reference escapes me, establishes the conditions under which asymtotics of the marginal distribution imply a well behaved limit. Perhaps a better discussion of the issues can be

[R] distance between distributions

Hi, This is more of a general stat question. I am looking for a easily computable measure of a distance between two empirical distributions. Say I have two samples x and y drawn from X and Y. I want to compute a statistics rho(x,y) which is zero if X = Y and grows as X and Y become less similar.
