Abstract: | Summary If X1, X2, ..., are i.i.d. random variables and Yn=Max(X1, ..., Xn); if for some sequences An, Bn, n=1, 2, ..., En(t)=AnY[nt]+Bn is such that En(1) weakly converges to a non degenerate limit distribution, then we prove that it is possible to construct a sequence of replicates of extremal processes E(n)(t) on the same probability space, such that d(En(.), E(n)(.))0 a.s., with the Levy metric. We give the rates of consistency of the approximations. |
